Does Gold-Plated Jewellery Tarnish? The Ultimate Guide

Does Gold-Plated Jewellery Tarnish?

Yes, gold-plated jewellery can tarnish, fade or lose some of its original colour over time.

Gold-plated jewellery is made by applying a layer of real gold over another metal. As that outer layer is exposed to everyday wear, friction, moisture, sweat and chemicals, it can gradually become thinner, allowing the metal underneath to become exposed.

Once the base metal is exposed, it can react with air and moisture and begin to tarnish. However, this does not mean that all gold-plated jewellery will tarnish quickly. How long the finish lasts depends on several factors, including the quality and thickness of the plating, the base metal underneath, how often the jewellery is worn and how it is cared for.

For example, gold plating can be applied over different materials such as stainless steel or brass, and each behaves differently over time. You may also see jewellery described as 14K gold-plated, 18K gold-plated or gold vermeil, which are not necessarily the same thing.

In this guide, we'll explain why gold-plated jewellery tarnishes, what affects its lifespan, whether it can get wet, the differences between common base metals, and the steps you can take to keep your jewellery looking its best for longer.

What Is Gold-Plated Jewellery?

Gold-plated jewellery is jewellery made from a base material that has been covered with a layer of gold or gold alloy. In modern manufacturing, this is commonly achieved through electroplating, an electrochemical process that deposits a thin metallic coating onto another material. [24]

Gold-plated jewellery consists of a layer of gold or gold alloy applied over another material.

What Do 14K and 18K Gold-Plated Mean?

When jewellery is described as 14K gold-plated or 18K gold-plated, the karat number refers to the fineness of the gold alloy used for the outer coating, not to the metal underneath.

The traditional karat system divides gold purity into 24 parts. 14K gold is 14 parts gold out of 24 [5], equivalent to approximately 58.5% gold, while 18K gold is 18 parts out of 24 [5], equivalent to 75% gold.

This does not mean that a piece described as 18K gold-plated is made entirely from 18K gold. Instead, an 18K gold alloy forms the surface coating while another material provides the structure underneath.

This distinction matters when comparing jewellery because two pieces may both appear gold in colour while having very different constructions.

At Nebu Valora, our Golden Hour Layers uses 14K gold-plated stainless steel, while our Pearl Drop Hoops uses 18K gold-plated stainless steel.

These examples also demonstrate why the words “gold-plated” should not be treated as a description of the entire material composition. The base metal, gold alloy and way the coating is applied are all relevant when understanding how a piece of jewellery is made.

Why Is Gold Used as a Coating?

Gold is valued for more than its appearance. It has high chemical stability and resistance to oxidation and corrosion [24], which is one reason gold coatings are also used in demanding technical applications such as electronics.

However, a gold coating should not be confused with an indestructible surface. The underlying material and the condition, thickness and wear of the coating still matter.

That becomes particularly important when answering the next question:

Why Does Gold-Plated Jewellery Tarnish?

Gold itself is highly resistant to oxidation and corrosion, which is one reason it is used as a protective surface coating. However, gold-plated jewellery is made from more than just gold. It consists of a gold or gold-alloy surface over another material, and the behaviour of the whole piece changes as that outer coating gradually wears.

In many cases, what people describe as their gold-plated jewellery “tarnishing” is actually a combination of surface wear, changes in the gold finish and reactions involving the metal underneath.

Research into gold coatings has shown that microscopic pores or imperfections can allow moisture and other corrosive substances to reach the underlying metal [1]. Once that happens, corrosion can occur beneath or through the gold coating.

Friction and Everyday Wear

Every time a piece of jewellery rubs against skin, clothing or another surface, a small amount of mechanical wear can occur.

Scientific studies of gold coatings have shown that friction and repeated contact can gradually wear gold-coated surfaces [2], with the durability of the coating depending on factors such as its structure, hardness, thickness and the material underneath.

This is why different types of jewellery can experience different levels of wear.

A bracelet, for example, may repeatedly rub against a desk, sleeve or wrist throughout the day, while a pair of earrings may experience considerably less direct abrasion.

Friction does not necessarily “tarnish” the gold itself. Instead, repeated abrasion can gradually reduce the integrity of the surface coating, making the underlying material more likely to become exposed.

Simple three-stage infographic

Sweat and Moisture

Human sweat contains water, salts and other chemical compounds. When a metal surface is repeatedly exposed to these substances, they can create conditions in which corrosion reactions occur.

Research examining brass in synthetic sweat found that chloride ions accelerated corrosion processes in the brass samples [3], including pitting and selective removal of zinc from the alloy.

This is particularly relevant when discussing gold-plated jewellery because brass is frequently used as a base material beneath gold plating.

However, it is important not to oversimplify this. The rate at which a particular piece changes will depend on its exact alloy, coating, construction and exposure conditions. Laboratory experiments on one brass composition cannot tell us exactly how quickly a different piece of jewellery will change.

Gold coatings provide an important barrier between the environment and the underlying metal. The problem becomes more significant when that barrier develops wear, pores or exposed areas.

A 2008 study examining porous gold coatings demonstrated that liquid reaching the substrate through pores in a gold layer could lead to corrosion of the metal underneath. [1]

What About Gold-Plated Stainless Steel?

Stainless steel behaves differently from brass because stainless steels can form a protective passive surface layer that gives them substantial corrosion resistance.

That does not mean a gold-plated stainless-steel piece is immune to wear. The gold coating can still gradually wear, but the behaviour of the exposed base metal may be different from that of brass.

We will examine this more closely later in this guide.

Does Sweat Damage the Gold Itself?

The answer is more complicated than simply saying that “sweat destroys gold”.

Gold is chemically very stable, and research using gold-containing jewellery materials has generally demonstrated very low gold release under standard artificial-sweat conditions. However, more recent laboratory research has shown that certain sulphur-containing compounds found in biological environments can promote measurable gold release under specific experimental conditions. [4]

For everyday jewellery care, the more useful point is that repeated sweat exposure combined with friction, moisture and eventual coating wear can contribute to deterioration of a plated surface over time.

This is also why jewellery worn during exercise may experience harsher conditions than jewellery worn occasionally.

Do Perfume, Lotion and Cosmetics Affect Gold-Plated Jewellery?

Gold-plated jewellery is also regularly exposed to products such as perfume, moisturiser, hairspray, sunscreen and cosmetics.

Because these products contain widely differing mixtures of alcohols, oils, salts, surfactants and other ingredients, it would be misleading to claim that every cosmetic product reacts with gold plating in exactly the same way.

The safest practical approach is therefore to minimise unnecessary chemical exposure, especially because a plated surface is not an infinitely thick layer of gold.

A useful rule is:

Apply perfume, skincare and cosmetics first, allow them to dry, and put your jewellery on afterwards.

This reduces the amount of product deposited directly onto the jewellery and also reduces the need for frequent cleaning.

Why Some Pieces Last Longer Than Others

There is no single answer to how quickly gold-plated jewellery will show signs of wear.

Its durability can be affected by several factors:

• the thickness and quality of the gold coating

• the composition of the gold alloy

• the base material underneath

• the quality and porosity of the coating

• how frequently the jewellery is worn

• how much friction it experiences

• exposure to sweat and moisture

• cleaning and storage habits

This is why two pieces described simply as “gold-plated” can perform differently over time.

The right cleaning method can help remove this build-up without causing more damage. See our guide on how to clean gold-plated jewellery without damaging it.

The next question is therefore an important one:

Does 18K Gold-Plated Jewellery Tarnish?

Yes, 18K gold-plated jewellery can tarnish or change in appearance over time. The important point is that “18K gold-plated” does not mean the entire piece is made from solid 18K gold — it means that an 18-karat gold alloy has been used for the surface coating.

18K gold contains 18 parts gold out of 24 [5], equivalent to 750 parts per thousand, or 75% gold. The remaining 25% consists of other metals used within the gold alloy.

That distinction matters because although gold itself is highly resistant to corrosion, an 18K gold alloy is not chemically identical to pure 24K gold.

Scientific research specifically examining decorative gold alloys — including 18-carat electroplated gold coatings — has shown that tarnish resistance can vary according to the composition of the gold alloy and the environment to which it is exposed. [6]

Why Can 18K Gold Plating Still Change Colour?

There are two different processes worth separating.

First, the gold-alloy surface itself can be affected by its environment. The behaviour of a gold alloy depends partly on the other metals present alongside the gold. Laboratory research into decorative gold alloys has demonstrated measurable differences in tarnish behaviour between different gold-alloy compositions. [6]

Second, the plating can gradually wear. As we discussed earlier, friction and repeated contact can reduce the integrity of a gold-coated surface over time. [2] Once areas of the underlying base metal become exposed, that metal may react differently to moisture, sweat and the surrounding environment.

So an item being labelled 18K gold-plated does not make it tarnish-proof.

It tells you the fineness of the gold alloy used for the coating. It does not tell you, by itself, how thick that coating is, what metal sits underneath it, how frequently the piece will be worn or the conditions it will be exposed to.

Does 18K Mean Better Than 14K Gold Plating?

Not necessarily.

18K gold contains a greater proportion of gold than 14K gold, but karat alone is not enough to predict how long a plated piece will retain its appearance.

Plating durability also depends on the coating itself, the base material, manufacturing process, friction, exposure and how the jewellery is cared for.

We will compare 14K and 18K gold plating more closely later, but the key point is simple:

Higher karat does not automatically mean longer-lasting plating.

18K Gold-Plated Jewellery at Nebu Valora

Several Nebu Valora pieces use 18K gold plating over stainless steel, including the Pearl Drop Hoops Earrings, Halo Circle Hoops Earrings and Golden Orbit Bracelet.

These are useful examples of why the full material description matters. Rather than simply saying “18K gold-plated”, the description tells you both the gold finish and the base material beneath it.

Next, we can make the same distinction with another common description:

Does 14K Gold-Plated Jewellery Tarnish?

Yes, 14K gold-plated jewellery can tarnish, fade or change in appearance over time. As with 18K gold plating, the term “14K” describes the gold alloy used for the outer coating — it does not mean that the entire piece is made from 14K gold.

In the UK hallmarking system, 14-carat gold corresponds to a fineness of 585 parts per thousand, or 58.5% gold. [5] The remainder of the alloy consists of other metals, which can influence properties such as colour, hardness and chemical behaviour.

Researchers studying jewellery gold alloys have confirmed that 14K gold is an alloy rather than pure gold, with metals such as silver, copper, cobalt and zinc potentially used alongside gold in jewellery compositions. [7]

This describes the gold alloy used for the plating — not the percentage of gold in the entire piece of jewellery.

Why Can 14K Gold-Plated Jewellery Tarnish?

There are again two separate issues to consider: the composition of the gold alloy at the surface and the gradual wear of the plating itself.

Scientific research into decorative 14K gold alloys has shown that tarnishing can involve reactions with the non-gold metals contained within the alloy.

One laboratory study examined several decorative gold alloys, including 14-carat gold-silver-copper and gold-silver-copper-zinc alloys, and found that sulphidation of the non-noble metals contributed to the formation of coloured tarnish films. [6]

It is important to be precise here: this research examined decorative 14K gold alloys rather than every type of modern 14K electroplated jewellery. However, it demonstrates an important principle — the metals alloyed with gold can affect how a gold surface reacts to its environment.

That means the word “14K” alone cannot tell you exactly how a particular plated piece will behave.

The Gold Plating Can Also Wear

Even when the gold-alloy surface initially resists visible tarnishing, the coating itself is still exposed to everyday friction.

Research on gold coatings shows that their microstructure, mechanical properties and surface quality influence their resistance to wear. [2]

As the plated surface gradually wears, small areas of the base material underneath may eventually become exposed. At that point, the behaviour of the base metal — whether stainless steel, brass or another material — becomes increasingly important.

This is why the complete material description tells you more than simply seeing “14K gold-plated”.

Is 14K Gold Plating Better Than 18K Gold Plating?

Neither should automatically be described as “better”.

18K contains a larger proportion of gold, while 14K contains a larger proportion of other alloying metals. Those differences can affect characteristics such as colour and material properties, but karat alone does not determine the lifespan of a plated piece.

How well the finish lasts also depends on:

• coating thickness and quality

• composition of the gold alloy

• base material

• manufacturing process

• friction and frequency of wear

• exposure to moisture and chemicals

• cleaning and storage

So you should not assume:

18K = automatically longer lasting

or

14K = automatically more durable

without knowing more about the construction of the piece.

14K Gold-Plated Jewellery at Nebu Valora

Nebu Valora uses 14K gold plating across different base materials.

For example, Golden Hour Layers Necklace is made using 14K gold-plated stainless steel, while the Golden Arc Necklace and  Pearl Curve Studs use 14K gold-plated eco-brass.

These pieces illustrate why identifying the base metal as well as the gold plating is useful when comparing jewellery.

That leads directly to our next question:

Does Gold-Plated Stainless Steel Tarnish?

Gold-plated stainless steel can change in appearance over time, but stainless steel itself is naturally more resistant to corrosion than many ordinary metals.

This is because stainless steel forms an extremely thin chromium-rich passive film [8] on its surface. This protective layer acts as a barrier between the metal and its environment, slowing the electrochemical reactions responsible for corrosion.

When stainless steel is covered with gold plating, however, the visible surface you see and touch is primarily the gold-alloy coating rather than the stainless steel underneath.

That means there are effectively two different layers to consider:

Gold-plated surface
↓
Stainless-steel base

The gold finish can gradually experience wear even though the stainless-steel base itself may remain comparatively corrosion resistant.

Why Is Stainless Steel Resistant to Corrosion?

The defining feature of stainless steel is its ability to form a protective surface film containing chromium oxides.

Research into corrosion-resistant metals describes stainless steels as alloys that spontaneously form a chromium-rich passive film, which acts as a protective barrier and greatly reduces the rate at which the underlying metal reacts with its environment.

Importantly, this film is extremely thin.

Research examining 316L stainless steel using surface-analysis techniques has measured its naturally formed oxide layer at only around 2 nanometres thick, [9] while still demonstrating its important protective role.

That helps explain why stainless steel can appear like an ordinary polished metal while having significantly different corrosion behaviour beneath the surface.

What Happens When the Gold Plating Starts to Wear?

The stainless steel underneath does not suddenly become exposed across the entire piece.

Instead, repeated friction can gradually affect particular areas of a plated surface — especially places that regularly touch skin, clothing or other objects.

As discussed earlier, scientific testing of gold coatings has shown that their surface characteristics and mechanical properties influence how they behave under friction and wear. [2]

This means areas that experience frequent rubbing may begin to show changes sooner than protected areas.

A bracelet, for example, may receive repeated contact against desks, sleeves and the wrist, while the pendant of a necklace may experience a different wear pattern.

If the coating becomes sufficiently worn, small areas of stainless steel beneath it may eventually become exposed.

Can Stainless Steel Underneath the Gold Corrode?

Yes — corrosion-resistant does not mean corrosion-proof.

The passive layer that gives stainless steel its corrosion resistance can break down under sufficiently aggressive environmental conditions.

A major scientific review of corrosion-resistant metals explains that protective passive films can break down locally, potentially resulting in pitting or crevice corrosion [8]. Environmental conditions, material composition and defects in the surface all influence this process.

Chloride-containing environments are particularly important in stainless-steel corrosion science. This is one reason repeated exposure to substances such as salt water and sweat should not automatically be treated as harmless simply because the base metal is stainless steel.

For everyday jewellery use, however, it is important to keep this in perspective: laboratory corrosion environments are often deliberately much harsher than normal day-to-day wear.

The existence of these corrosion mechanisms does not mean a stainless-steel necklace will suddenly rust after contact with perspiration.

It means that stainless steel has excellent corrosion resistance — not unlimited corrosion resistance.

Does the Gold Coating Protect the Stainless Steel?

While intact, a metallic coating can provide a physical barrier between the underlying material and its environment.

However, coatings are rarely best thought of as permanently perfect barriers.

As we discussed earlier, microscopic pores, wear or damage can create pathways through which moisture can eventually reach the material underneath. [1]

This is why the condition and quality of the plated surface matter alongside the corrosion resistance of the base metal.

There is also direct scientific research involving gold electroplating over stainless steel.

A 2024 peer-reviewed study examining 316L stainless steel compared different electroplating processes and successfully deposited gold layers directly onto stainless-steel substrates. The researchers measured the gold coatings and investigated how the plating system affected metal release under standardized testing conditions.

Although that research was conducted for metal-release testing rather than jewellery tarnish specifically, it provides useful experimental evidence of how gold coatings and stainless-steel substrates behave as a combined layered system. [10]

Is Gold-Plated Stainless Steel Good for Jewellery?

From a materials perspective, stainless steel offers several characteristics that make it useful as a jewellery base, particularly its mechanical strength and corrosion resistance.

Gold plating can then provide the desired gold appearance without requiring the entire piece to be made from solid gold.

But the important distinction remains:

The stainless steel may be highly corrosion resistant while the decorative gold finish can still gradually wear.

This is why proper care remains useful even when a piece has a stainless-steel base.

Gold-Plated Stainless Steel at Nebu Valora

A number of Nebu Valora pieces combine stainless steel with a gold-plated finish.

These include:

• Golden Hour Layers — 14K gold-plated stainless steel

• Luna Pearl Crescent Necklace — 18K gold-plated stainless steel

• Pearl Drop Hoops — 18K gold-plated stainless steel

• Crystal Pearl Hoops — 18K gold-plated stainless steel

• Halo Circle Hoops — 18K gold-plated stainless steel

• Golden Orbit Bracelet — 18K gold-plated stainless steel

• Eclipse Mesh Bracelet — 18K gold-plated stainless steel

• Butterfly Grace Bracelet — 18K gold-plated stainless steel

Stainless steel is not the only base material used beneath gold plating, however.

Nebu Valora also uses gold-plated eco-brass, which behaves differently when exposed to the environment.

That brings us to:

Does Gold-Plated Brass Tarnish?

Yes. Gold-plated brass can tarnish or change colour over time, particularly if the gold coating becomes worn and the brass underneath is exposed.

Brass is primarily a copper-zinc alloy, and unlike gold, the metals within brass can react with their environment. One corrosion process associated with brass is called dezincification, in which zinc is selectively removed from the alloy under certain conditions. [11]

This does not mean that every brass jewellery piece will visibly corrode or tarnish at the same rate. Brass alloys vary in composition, and the behaviour of a finished piece also depends on its plating, exposure and care.

The gold coating provides an important barrier between the brass and its surroundings. As long as that coating remains intact, direct exposure of the brass underneath is reduced.

However, as we have already seen, wear, microscopic pores or damage to a gold coating can allow the underlying metal to come into contact with moisture and its surrounding environment. [1]

What Happens When Brass Is Exposed to Sweat?

This is particularly relevant to jewellery because necklaces, earrings and bracelets regularly come into contact with skin.

A peer-reviewed study specifically investigated brass exposed to synthetic human sweat. Researchers found that chloride ions accelerated the active dissolution of brass and contributed to both pitting corrosion and dezincification. [3]

The study also identified corrosion products containing copper compounds on the brass surface.

This does not mean normal perspiration will immediately damage a brass jewellery piece. The experiment used controlled laboratory conditions to study the corrosion mechanism.

But it does demonstrate why repeated sweat exposure becomes more relevant once the protective gold surface is worn or compromised.

Can Brass Actually Tarnish From Synthetic Sweat?

Yes.

Another scientific study, conducted by researchers from Swansea University and the Royal Mint, deliberately exposed brass samples to synthetic sweat using a recognised testing method.

The researchers observed changes to the chemistry of the brass surface over the testing period and described the formation of a surface corrosion layer following synthetic-sweat exposure. [12]

This provides particularly useful evidence for jewellery because it demonstrates that brass can undergo measurable surface changes in an environment designed to simulate human perspiration.

Again, it should not be interpreted as a prediction of how many days, months or years a particular piece of jewellery will last. Laboratory testing is designed to produce controlled and measurable conditions, not replicate every person's everyday wear exactly.

What Is Dezincification?

Because the word sounds technical, it is worth explaining simply.

Brass contains both copper and zinc. Under certain corrosive conditions, zinc can be preferentially removed from the alloy.

This process is known as dezincification.

A scientific review of brass corrosion explains that dezincification can occur through processes involving selective zinc dissolution, with factors such as alloy composition and environmental conditions influencing susceptibility. [11]

For jewellery, you do not need to see dramatic structural corrosion for a surface change to matter. Even relatively small changes to exposed brass can affect its colour and appearance.

This is one reason a piece may eventually appear darker, duller or different in colour where plating has worn.

Does This Mean Gold-Plated Brass Is Bad for Jewellery?

No.

Brass is widely used as a base material because it can be shaped into detailed designs and provides a suitable surface for decorative finishes.

The important point is simply to understand what you're buying.

With gold-plated brass:

• The gold coating provides the visible finish.
• The brass underneath provides the structure.

If the plating gradually wears, the behaviour of the brass base becomes more relevant.

This is also why proper jewellery care can help preserve the appearance of a plated piece for longer.

What About Eco-Brass?

Some Nebu Valora pieces use eco-brass as their base material.

The term “eco-brass” can refer to brass materials produced with particular environmental or compositional considerations, but it should not be treated as one universal alloy specification unless the exact alloy composition is known.

For that reason, we should not claim that every eco-brass formulation has exactly the same corrosion behaviour.

For the purposes of caring for gold-plated jewellery, the sensible approach is still to protect the gold-plated surface and minimise unnecessary exposure to moisture, sweat and harsh chemicals.

Gold-Plated Eco-Brass at Nebu Valora

Nebu Valora currently uses gold-plated eco-brass in several pieces:

• Golden Arc Necklace — 14K gold-plated eco-brass

• Infinity Stone Necklace — 14K gold-plated eco-brass

• Pearl Curve Studs — 14K gold-plated eco-brass

• Lattice Gold Studs — 18K gold-plated eco-brass

We have now looked at the two main base materials used beneath Nebu Valora's gold plating: stainless steel and eco-brass.

But there is another question jewellery owners ask constantly:

Can Gold-Plated Jewellery Get Wet?

Yes, gold-plated jewellery can get wet, but repeated or prolonged exposure to water is best avoided if you want to preserve the plated finish for as long as possible.

An occasional splash is very different from repeatedly showering, swimming or exercising while wearing a piece.

The reason is not simply that “water damages gold”. Pure metallic gold is highly chemically stable. The issue with gold-plated jewellery is that it is a layered material: a thin gold-alloy surface sits over another metal, and wear, microscopic pores or damage can eventually allow liquid to reach the material underneath. [1]

Is Ordinary Water Bad for Gold-Plated Jewellery?

Water alone should not automatically be treated as though it instantly removes gold plating.

In fact, research using gold-containing jewellery materials under standard artificial-sweat conditions has historically found extremely low or undetectable gold release. [15]

However, everyday water exposure rarely involves chemically pure water.

Showering may introduce:

• soap

• shampoo and conditioner

• body wash

• dissolved minerals

• cosmetics and skincare residues

Swimming introduces additional substances, particularly chlorides in seawater and disinfecting chemicals in swimming pools.

This is why avoiding repeated wetting is a sensible way of reducing unnecessary chemical exposure and cleaning.

Can You Shower With Gold-Plated Jewellery?

You can physically shower while wearing it, but regularly doing so is not recommended if your priority is preserving the finish.

The concern is repeated exposure rather than one accidental shower.

Water, soaps and personal-care products can remain on the jewellery surface, while repeated washing, rubbing and drying add further mechanical contact.

Over time, those conditions occur alongside the same friction and coating wear discussed earlier in this guide.

What About Swimming in the Sea?

Seawater deserves more caution because it contains a high concentration of dissolved salts, including chloride ions.

Chlorides are well established in corrosion science as an important factor in localized corrosion of metals.

For stainless steel specifically, laboratory research has shown that chloride ions can alter its protective passive surface film and produce a less protective passive state. [13]

For brass, research using synthetic sweat has also shown that chloride ions can accelerate dissolution, pitting and dezincification. [3]

That means seawater becomes particularly relevant if areas of the underlying stainless steel or brass have become accessible through worn or damaged plating.

This does not mean a brief splash of seawater will instantly destroy a piece of jewellery.

It does mean that regular swimming in salt water while wearing gold-plated jewellery creates a more aggressive environment than keeping the piece dry.

If your jewellery does come into contact with seawater, rinsing away salt residue with clean fresh water and drying the piece gently is preferable to allowing salt deposits to remain on the surface.

Can You Swim in a Pool With Gold-Plated Jewellery?

Swimming pools introduce a different chemical environment.

Chlorinated solutions have long been studied in relation to gold jewellery alloys. Research involving commercial 18K gold jewellery alloys found that their corrosion behaviour depended both on the alloy composition and the chemical solution to which they were exposed, [14] with chlorinated environments capable of contributing to environmental attack under laboratory conditions.

The experiment involved solid 18K jewellery alloys rather than modern gold-plated stainless-steel or brass jewellery, so we should not use it to predict exactly what will happen to a plated piece.

It does, however, reinforce an important point:

Gold alloys are not completely unaffected by every chemical environment simply because they contain gold.

For plated jewellery, pool exposure also matters because the coating is thin and the underlying material may eventually become accessible.

The safest approach is therefore simple:

Remove gold-plated jewellery before swimming in a chlorinated pool.

What About Sweat?

Sweat is also very different from plain water.

Human perspiration contains salts and organic compounds, which is why scientists use artificial sweat solutions when studying metal release from jewellery.

A 2026 peer-reviewed study tested actual gold-plated earrings in a modified artificial-sweat solution. Under those specific laboratory conditions, researchers detected measurable gold release from some of the earrings and metal release from the materials underneath the plating. [4]

This does not mean ordinary exercise will immediately remove a gold coating.

It does show that the combination of moisture, salts, skin chemistry and prolonged contact is more complex than simply exposing jewellery to pure water.

For jewellery you want to preserve, removing it before heavy exercise is therefore a sensible precaution.

What Should You Do If Gold-Plated Jewellery Gets Wet?

There is no need to panic if your jewellery is accidentally splashed or gets caught in the rain.

A practical approach is:

1. Remove the jewellery if practical.

2. Gently blot away moisture with a soft cloth.

3. Allow the piece to dry completely before storing it.

4. Avoid aggressive rubbing or abrasive polishing.

5. If it has been exposed to salt water, remove salt residue with clean fresh water and dry it carefully.

The goal is not to treat gold-plated jewellery as something that can never touch water.

It is simply to reduce repeated and unnecessary exposure when you want the finish to remain looking its best.

The next question naturally follows:

How Long Does Gold-Plated Jewellery Last?

There is no single number of months or years that accurately describes how long all gold-plated jewellery will last.

Two pieces can both be labelled “gold-plated” yet behave very differently because the durability of the finish depends on the coating itself, the material underneath it and how the jewellery is worn.

Scientific wear testing of gold coatings has shown that differences in their surface structure and mechanical properties can significantly affect wear behaviour. [2]

Other research on gold-alloy coatings has also shown that adhesion, coating thickness, composition and the conditions in which the coated material is used all influence how well the surface survives repeated contact. [16]

This is why claims such as “gold-plated jewellery lasts exactly two years” should be treated cautiously. That may describe someone's experience with a particular product, but it is not a universal lifespan for gold plating.

Gentle cleaning can also help protect the finish. Read our guide to cleaning gold-plated jewellery safely.

What Affects How Long Gold Plating Lasts?

Several factors work together.

1. The Thickness of the Gold Coating

Gold plating is a surface coating, and coatings can be produced at different thicknesses.

As a general materials principle, the amount of coating available before wear reaches the substrate is relevant to durability. However, thickness alone is not enough to tell you exactly how long a plated piece will last.

The coating's hardness, adhesion, microstructure and the conditions under which it is worn also matter.

Research examining gold-based coatings for fashion and luxury applications has demonstrated that even very thin coatings can show useful wear resistance when the coating system has good adhesion and appropriate mechanical properties. [16]

2. How Often You Wear the Jewellery

A necklace worn once a month does not experience the same amount of contact as a bracelet worn every day.

Repeated contact creates more opportunities for friction.

Laboratory studies of gold coatings demonstrate that repeated sliding contact progressively alters coated surfaces and can eventually expose the material underneath. [2]

For that reason, jewellery worn every day would normally be expected to accumulate more physical wear than an equivalent piece worn only occasionally.

That does not allow us to predict an exact lifespan — it simply explains why frequency of wear matters.

3. Where You Wear It

The type of jewellery also affects the amount of friction it encounters.

A bracelet may repeatedly contact:

• your wrist

• sleeves

• desks and tables

• bags or other objects

A necklace pendant may encounter considerably less abrasion.

Earrings may experience less contact still, depending on their design.

This is one reason two pieces made using similar plating can age differently even when owned by the same person.

4. Sweat, Water and the Environment

As we covered earlier, the environment around a plated surface matters.

Gold itself is highly stable, but the jewellery is a layered system. If wear, pores or damage eventually allow the environment to reach the substrate, corrosion processes can occur underneath or through the coating. [1]

Scientific testing has demonstrated this mechanism in porous gold coatings, where exposure of the underlying substrate resulted in corrosion beneath the gold layer. [1]

This is another reason an exact calendar lifespan is impossible to give.

Someone wearing a piece occasionally in relatively mild conditions is exposing it to a very different environment from someone wearing the same type of jewellery through daily exercise, swimming and repeated washing.

5. How the Jewellery Is Stored and Cleaned

Wear does not occur only while jewellery is being worn.

Pieces stored rubbing against one another can experience scratching, while aggressive polishing can remove material from a plated surface.

Gold plating should therefore be treated differently from a thick piece of solid metal that can tolerate repeated heavy polishing.

Later in this guide, we will look at simple ways to reduce unnecessary wear and help gold-plated jewellery retain its appearance for longer.

Does More Expensive Gold-Plated Jewellery Automatically Last Longer?

Not necessarily.

Price can reflect many things, including:

• design

• branding

• craftsmanship

• stones or pearls

• manufacturing location

• packaging

• coating process and materials

A higher price by itself does not tell you the thickness, adhesion or wear resistance of a gold coating.

The material specification is therefore more useful than price alone when trying to understand how a piece is constructed.

Can Gold-Plated Jewellery Last for Years?

Yes, it can — but it would be misleading to promise that every plated piece will.

Jewellery worn occasionally and cared for carefully may retain its finish for a long time, while heavily worn pieces can show visible changes considerably sooner.

Scientific wear studies reinforce why: gold coatings do not all respond identically to repeated friction. Their composition and surface properties influence how quickly wear develops. [2]

So instead of asking:

“Exactly how many years will this last?”

a more useful question is:

“What can I do to reduce unnecessary wear?”

That brings us to the next section:

How to Stop Gold-Plated Jewellery Tarnishing

You cannot guarantee that gold-plated jewellery will never change over time, but you can reduce unnecessary wear and help the finish stay looking its best for longer.

The most useful approach is to protect the plated surface from the things that can accelerate wear: repeated friction, unnecessary moisture, sweat, harsh environments and aggressive cleaning.

Scientific wear testing has shown that the surface structure and mechanical properties of gold coatings influence how well they resist repeated friction and wear. [2]

1. Reduce Unnecessary Friction

Gold plating is a surface layer, so repeated rubbing gradually matters.

Research into gold coatings has shown that friction and sliding contact can progressively alter the surface and reduce its wear resistance. [2]

You cannot avoid all friction when wearing jewellery — nor should you try to — but you can avoid unnecessary abrasion.

For example:

• Remove bracelets before activities where they may repeatedly scrape against hard surfaces.

• Avoid storing several pieces tangled together.

• Do not scrub plated jewellery with abrasive brushes or polishing materials.

This does not mean gold-plated jewellery is fragile. It simply means that reducing unnecessary mechanical wear can help preserve the finish.

2. Follow the Water-Care Instructions for the Specific Piece

Not every gold-plated jewellery piece has the same construction or water resistance.

Some stainless-steel pieces may be specifically designed and tested for water exposure, while other plated pieces are better kept dry. The most accurate approach is therefore to follow the care instructions for the individual piece, rather than assuming that all gold-plated jewellery behaves identically.

For jewellery that is not specifically described as water-safe or waterproof, reducing prolonged water exposure is the more conservative approach.

As discussed earlier, microscopic pores or worn areas in a metallic coating can allow liquid to reach the material underneath. [1]

If jewellery gets caught in the rain or is accidentally splashed, there is no reason to panic. Gently dry it afterwards rather than aggressively rubbing the surface.

3. Be Mindful of Sweat

Sweat contains water, salts and other compounds.

Laboratory research on brass exposed to synthetic sweat found that chloride ions accelerated corrosion processes including pitting and dezincification. [3]

That becomes especially relevant if the gold coating has become worn enough for the base material underneath to be exposed.

For pieces that are not specifically designed for heavy sweat or water exposure, removing them before intense exercise can reduce unnecessary exposure.

4. Put Jewellery On After Perfume and Skincare

Perfume, moisturiser, sunscreen, hairspray and cosmetics can leave residues on jewellery.

Rather than trying to predict how every possible cosmetic formulation will interact with every plating system, a simple routine is useful:

Apply perfume, skincare and cosmetics first. Allow them to settle or dry, then put your jewellery on.

This reduces the amount of product deposited directly onto the jewellery and may also reduce how frequently the piece needs cleaning.

5. Wipe Jewellery Gently After Wearing

After wearing a piece, a gentle wipe with a clean, soft cloth can remove some surface moisture, oils and residues.

The important word is gentle.

Heavy polishing is unnecessary for most gold-plated jewellery because the finish you are trying to clean is itself a surface coating.

Repeated mechanical contact is one of the factors known to affect gold-coating wear. [2]

6. Store Pieces Separately

Jewellery can experience friction even while sitting in a jewellery box.

Chains can rub against other chains, earrings can scratch neighbouring pieces and harder components can repeatedly contact plated surfaces.

Where practical:

• Store pieces separately.

• Close clasps before storing chains.

• Keep chains untangled.

• Use soft pouches or separate compartments.

• Keep jewellery somewhere clean and dry.

The aim is simple: reduce unnecessary surface-to-surface rubbing while the jewellery is not being worn.

7. Avoid Aggressive Cleaning

Gold-plated jewellery generally does not need heavy polishing, abrasive powders or stiff brushes.

Because the gold finish is a coating, aggressive mechanical cleaning can create additional wear rather than helping preserve it.

For the safest way to remove dirt without damaging the finish, see our guide to cleaning gold-plated jewellery.

When cleaning is necessary, use the gentlest method appropriate for the materials contained in the piece.

This becomes especially important when jewellery also contains pearls, mother of pearl, crystals or other decorative materials that may have their own care requirements.

We will look at cleaning in more detail in the next section.

Can You Completely Prevent Gold Plating From Fading?

Not necessarily.

A plated surface is not the same as a piece made entirely from solid gold, and normal wear can eventually change its appearance.

The purpose of good jewellery care is therefore not to promise that the finish will remain unchanged forever.

It is to reduce avoidable wear.

A useful routine is simple:

• Wear it. Enjoy it.
• Keep it clean.
• Store it carefully.
• Avoid harsher conditions than necessary.

Next:

How Should You Clean Gold-Plated Jewellery?

Gold-plated jewellery should be cleaned gently.

The aim is to remove oils, moisture and everyday residue without unnecessarily rubbing away the plated surface.

For the full step-by-step method, read How to Clean Gold-Plated Jewellery Without Damaging It.

Because gold plating is a surface coating, aggressive polishing and abrasive cleaning can create additional wear rather than protecting the jewellery. Research into gold coatings shows that repeated mechanical contact and friction affect coating wear. [2]

The safest cleaning method also depends on what else the piece contains. Jewellery with pearls, mother of pearl or other delicate materials may require different care from a simple gold-plated metal piece.

1. Check What the Jewellery Is Made From

Before cleaning, check the materials in the piece.

A gold-plated necklace containing only metal and crystals may tolerate a different cleaning method from earrings containing freshwater pearls.

This matters because some gemstones and organic materials are more sensitive to chemicals, heat, scratching or aggressive cleaning.

For example, the Gemological Institute of America notes that pearls are relatively soft and can be damaged by chemicals including perfume and cosmetics. [17]

For Nebu Valora pieces containing freshwater pearls or mother of pearl, the care requirements of those materials should therefore be considered alongside the gold plating.

2. Start With a Soft Cloth

For routine cleaning, you often do not need a complicated cleaning solution.

Use a clean, soft, lint-free cloth and gently wipe the surface.

This can help remove:

• skin oils

• fingerprints

• light moisture

• cosmetic residue

• everyday surface dirt

Do not scrub.

The Gemological Institute of America recommends wiping pearl jewellery with a very soft, clean cloth after wearing it. [17]

A gentle wipe is also useful for plated surfaces because it avoids unnecessary abrasion.

3. If More Cleaning Is Needed, Keep It Gentle

For gold-plated jewellery that is suitable for contact with water and does not have materials requiring different care, a small amount of mild soap and lukewarm water can be used for a more thorough clean.

A simple method is:

1. Add a small amount of mild soap to lukewarm water.

2. Dampen a soft cloth.

3. Gently wipe the jewellery.

4. Remove any remaining soap residue carefully.

5. Dry the piece completely with a clean, soft cloth.

Professional jewellery-care guidance for gold-plated jewellery similarly recommends mild soap, soft materials and avoiding aggressive cleaning. [18]

Do not assume every piece should be soaked.

Jewellery containing pearls, adhesives, delicate stones or other components may require more specific care.

4. Do Not Scrub the Plating

It can be tempting to scrub jewellery when it looks dull, particularly around chains, clasps and detailed surfaces.

But stronger cleaning is not necessarily better cleaning.

Gold plating is the surface you are trying to preserve.

Laboratory wear research demonstrates that friction progressively changes gold-coated surfaces. [2]

For that reason, avoid using unnecessary pressure or stiff brushes on plated areas.

5. Avoid Abrasive Home Cleaning Methods

Some popular jewellery-cleaning suggestions found online are designed to remove tarnish or polish solid metal.

That does not automatically make them appropriate for a plated surface.

Avoid using abrasive substances such as:

• toothpaste

• abrasive cleaning powders

• scouring products

• rough cloths

• aggressive metal polishes

The GIA specifically warns that abrasives found in products such as some metal polishes and toothpaste can erode metal and scratch gemstones. [19]

With gold-plated jewellery, there is an additional reason for caution: the surface being polished is a relatively thin gold coating.

6. Be Careful With Ultrasonic and Steam Cleaners

Ultrasonic jewellery cleaners use vibration to remove dirt from difficult-to-reach areas.

They can be useful for some jewellery, but they are not suitable for every material.

Pearls should not be placed in ultrasonic or steam cleaners, [17] according to the GIA.

Because Nebu Valora has several pieces containing freshwater pearls and mother of pearl, a home ultrasonic cleaner should not be treated as a universal cleaning method for the collection.

When you are uncertain about a particular piece, follow its individual care instructions instead.

7. Dry Jewellery Properly After Cleaning

Do not leave unnecessary moisture sitting on a piece after cleaning.

Use a soft cloth to gently remove water and allow the jewellery to dry completely before putting it away.

Pay particular attention to:

• clasps

• chain links

• stone settings

• small crevices

There is no need to rub vigorously. The purpose is simply to remove remaining moisture.

8. How Often Should Gold-Plated Jewellery Be Cleaned?

There is no universal cleaning schedule.

A piece worn regularly may accumulate oils and cosmetic residue more quickly than jewellery worn only occasionally.

Instead of cleaning according to an arbitrary weekly or monthly timetable, clean the jewellery when it needs it.

A gentle wipe after wearing is often enough for routine care.

More thorough cleaning should be reserved for when dirt or residue has actually accumulated.

This avoids cleaning the surface more frequently than necessary.

What If Cleaning Does Not Restore the Gold Colour?

This is an important distinction.

Sometimes jewellery looks dull because there is residue sitting on top of the gold surface.

That can potentially be cleaned away.

But if the gold coating itself has worn sufficiently for the material underneath to become visible, cleaning cannot recreate the missing gold layer.

The US Federal Trade Commission explains that gold plating eventually wears away and that the rate depends partly on how the item is worn and the thickness of the plating. [20]

If the colour change results from significant plating wear rather than dirt, the long-term solution may be professional replating, rather than stronger cleaning.

That is why increasingly aggressive polishing is not necessarily the answer when a plated piece stops looking as it once did.

Next:

Gold-Plated vs Gold Vermeil

Gold vermeil is a type of gold-plated jewellery, but not all gold-plated jewellery is vermeil.

The main difference is what sits underneath the gold and, under recognised definitions such as the US Federal Trade Commission's guidance, the required thickness and fineness of the gold coating.

Gold-plated jewellery can use a variety of base materials, including stainless steel and brass.

Gold vermeil uses sterling silver as its base metal. Under FTC guidance, a product described as vermeil consists of sterling silver coated on its significant surfaces with gold or gold alloy of at least 10K fineness, with a minimum thickness equivalent to 2.5 microns of fine gold. [21]

What Is Gold-Plated Jewellery?

Gold-plated jewellery consists of a base material covered with a layer of gold or gold alloy.

As we have seen throughout this guide, that base material might be:

• stainless steel

• brass

• sterling silver

• another suitable metal

The gold layer gives the jewellery its gold appearance while the material underneath provides most of the structure of the piece.

This means the words “gold-plated” alone do not tell you what the base metal is.

You need to look at the individual product specification.

For example, Nebu Valora's Golden Hour Layers uses 14K gold-plated stainless steel, while several other pieces in the collection use gold-plated eco-brass.

What Is Gold Vermeil?

Gold vermeil follows a more specific construction.

The base is sterling silver, rather than stainless steel or brass, and the silver is covered with gold.

The FTC describes vermeil as a special type of gold-plated product with a sterling-silver base. [20]

Sterling silver itself contains at least 92.5% silver, [20] which is why it is commonly marked 925.

Under the FTC's jewellery guidance, the gold used for vermeil must be at least 10K and the coating must meet the equivalent of a 2.5-micron fine-gold thickness. [21]

It is important to recognise that this is a specific US regulatory definition. Terminology and legal requirements can differ between countries, so the actual material specification supplied by the jeweller remains important.

Gold-Plated vs Gold Vermeil: The Main Differences

Does Gold Vermeil Last Longer Than Ordinary Gold-Plated Jewellery?

It can, but the word “vermeil” alone does not allow us to predict an exact lifespan.

One important difference is that the FTC definition of vermeil specifies a substantial gold coating: the equivalent of at least 2.5 microns of fine gold. [21]

However, coating thickness is only one part of durability.

Scientific studies of metallic coatings show that coating thickness, the condition of the underlying surface and the strength of the bond between coating and substrate can all influence coating life and wear behaviour. [22]

More recent research on gold coatings likewise demonstrates that microstructure and mechanical properties affect wear resistance. [2]

So it would be too simplistic to say:

“Vermeil always lasts longer than every other type of gold-plated jewellery.”

A well-made gold-plated stainless-steel piece, for example, has a completely different construction from a poorly produced coating on another material.

The full specification matters.

Can Gold Vermeil Tarnish?

Yes.

Vermeil still has a gold coating over another metal.

The outer gold layer can gradually experience wear, and the sterling silver underneath can tarnish if it becomes exposed.

The FTC's historical review of the vermeil standard specifically recognised that the sterling-silver base can be susceptible to discoloration and that the gold coating acts as a barrier over it. [23]

This does not mean vermeil will quickly tarnish. It simply means that it should not be described as permanently tarnish-proof.

What Happens When Vermeil Wears?

When ordinary gold plating wears, the material that becomes visible depends on its base.

With vermeil, the material underneath is sterling silver.

This creates an important practical difference.

If the gold surface eventually becomes thin or worn in certain areas, you may begin to see the cooler colour of silver underneath rather than brass or stainless steel.

The silver itself can also tarnish when exposed to the surrounding environment.

As with other plated jewellery, how quickly this becomes noticeable depends on factors such as:

• frequency of wear

• friction

• coating quality

• coating thickness

• exposure conditions

• how the piece is handled and stored

A Nebu Valora Gold Vermeil Example

Nebu Valora's Baroque Pearl Bracelet is made using 18K gold vermeil with freshwater baroque pearls.

That means its construction is different from a piece such as the Golden Hour Layers, which uses 14K gold plating over stainless steel.

Neither construction should automatically be considered universally “better”.

They use different base materials and coating systems, and each can be suitable for jewellery depending on the design, intended wear and manufacturing specification.

So, Which Is Better: Gold-Plated or Gold Vermeil?

There is no single answer based only on those two labels.

Vermeil gives you a precious-metal sterling-silver base and, where the FTC definition applies, a defined minimum gold-coating specification.

Other gold-plated jewellery can offer different advantages depending on the base material. Stainless steel, for example, has its own corrosion-resistant properties, while brass allows manufacturers to create detailed jewellery designs in different forms.

What matters most is understanding what the piece is actually made from rather than assuming that one label automatically guarantees how long it will last.

Next:

Frequently Asked Questions About Gold-Plated Jewellery

Does Gold-Plated Jewellery Tarnish?

Yes, gold-plated jewellery can tarnish, fade or change colour over time.

Gold itself is highly resistant to corrosion, but plated jewellery contains more than just gold. As the outer coating experiences wear, pores or damage, the material underneath can become increasingly exposed to the surrounding environment. [1]

How quickly this happens depends on the construction of the piece, frequency of wear, friction, exposure and care.

How Long Does Gold-Plated Jewellery Last?

There is no universal lifespan for gold-plated jewellery.

Scientific research shows that the wear behaviour of gold coatings is influenced by their microstructure and mechanical properties. [2]

A piece worn occasionally and treated gently may retain its appearance considerably longer than one exposed to heavy daily friction.

Claims that all gold-plated jewellery lasts a specific number of months or years should therefore be treated cautiously.

Can You Shower With Gold-Plated Jewellery?

That depends on the individual piece.

Some gold-plated jewellery may be specifically designed or tested for water exposure, while other pieces are better kept dry.

For jewellery that is not specifically described as shower-safe or waterproof, removing it before regular showering is the more conservative approach.

Repeated exposure also introduces more than water alone — including soaps, shampoos and other products.

Can You Wear Gold-Plated Jewellery Every Day?

Yes, but more frequent wear generally means more opportunities for friction.

Laboratory testing of gold coatings demonstrates that repeated sliding contact progressively changes the plated surface. [2]

That does not mean gold-plated jewellery should only be worn occasionally. It simply means that a frequently worn piece may accumulate surface wear more quickly than an equivalent piece reserved for occasional use.

Does 18K Gold-Plated Jewellery Tarnish?

Yes.

18K describes the gold alloy used in the coating; it does not mean the entire piece is solid 18K gold.

18K gold contains 75% gold, with the remainder made up of other metals.

Even though gold itself is highly stable, the plated surface can still experience wear and the material underneath can eventually become exposed.

Does 14K Gold-Plated Jewellery Tarnish?

Yes.

14K gold contains roughly 58.5% gold under the commonly used 585 fineness standard, with other metals making up the remainder. [5]

The fact that a coating is 14K does not make it permanently resistant to wear.

As with 18K plating, durability depends on the complete coating system and how the jewellery is used.

Does Gold-Plated Stainless Steel Tarnish?

It can change appearance over time.

Stainless steel itself has good corrosion resistance because it develops a thin protective passive film, but the gold coating sitting above it can still experience wear.

Once the plated surface becomes worn or damaged, the appearance of the jewellery may change.

This is why gold-plated stainless steel should not automatically be described as permanently tarnish-proof.

Does Gold-Plated Brass Tarnish?

Yes, particularly if wear allows the brass underneath to become exposed.

Brass is primarily a copper-zinc alloy, and laboratory research has demonstrated that it can undergo corrosion processes when exposed to synthetic sweat. [3]

The gold coating acts as a barrier between the brass and the surrounding environment, but that barrier can gradually experience wear.

Is Gold Vermeil the Same as Gold-Plated Jewellery?

Gold vermeil is a type of gold-plated jewellery, but it has a more specific construction.

Under US FTC guidance, vermeil uses a sterling-silver base coated with gold or gold alloy of at least 10K fineness and a minimum coating equivalent to 2.5 microns of fine gold. [21]

Other gold-plated jewellery can use base materials such as stainless steel or brass.

Can Gold Vermeil Tarnish?

Yes.

Gold vermeil still consists of a gold coating over another metal.

If the gold coating becomes sufficiently worn, the sterling silver underneath can become exposed and may tarnish.

This does not mean vermeil tarnishes quickly; it simply means it should not be treated as permanently immune to changes in appearance.

Can You Clean Tarnish From Gold-Plated Jewellery?

Sometimes — but it depends on what has caused the colour change.

If the jewellery looks dull because of surface oils, dirt or residue, gentle cleaning may improve its appearance.

If the gold coating itself has worn away, however, cleaning cannot recreate the missing gold layer.

The FTC notes that gold plating eventually wears away and that the rate depends partly on how the item is worn and the thickness of the plating. [20]

Avoid responding to colour changes with increasingly aggressive polishing, as this can create additional wear.

Our gold-plated jewellery cleaning guide explains the gentle method to use instead.

How Can You Help Gold-Plated Jewellery Last Longer?

Keep the routine simple:

• Reduce unnecessary rubbing and scratching.

• Follow the water-care instructions for the individual piece.

• Be mindful of heavy sweat exposure.

• Apply perfume and skincare before putting jewellery on.

• Wipe pieces gently after wearing.

• Store jewellery separately where practical.

• Avoid abrasive cleaning.

Good care cannot guarantee that a plated surface will remain unchanged forever, but it can help reduce avoidable wear.

Next:

Final Thoughts: Does Gold-Plated Jewellery Tarnish?

Yes — gold-plated jewellery can tarnish, fade or change colour over time, but that does not mean every piece will change at the same rate.

Gold itself is highly resistant to corrosion. The important difference with plated jewellery is that the gold forms a surface layer over another material.

As that surface experiences normal wear, the appearance of the jewellery can gradually change. The FTC notes that gold plating eventually wears away and that the rate depends partly on how the item is worn and the thickness of the plating. [20]

How long a piece retains its original appearance depends on several factors working together, including:

• the quality and construction of the plating

• the base material underneath

• how frequently the jewellery is worn

• the amount of friction it experiences

• exposure to water, sweat and other substances

• how it is cleaned and stored

Scientific research into gold coatings also shows that their surface structure and mechanical properties influence wear behaviour. [2]

That is why there is no single answer to questions such as “How long will gold plating last?” or “Will gold-plated jewellery tarnish after one year?”

Two pieces can both be described as gold-plated while having very different materials, coating systems and patterns of use.

The Most Important Thing to Remember

Gold-plated jewellery is designed to be worn and enjoyed.

You do not need to be afraid of touching it, wearing it or occasionally getting it wet.

Instead, focus on avoiding unnecessary wear.

Follow the care instructions for the individual piece, clean it gently, store it carefully and be aware that different materials may have different requirements.

When buying gold-plated jewellery, look beyond the words “gold-plated” and check what the piece is actually made from.

Is the base stainless steel, brass or sterling silver?

Is it 14K or 18K gold-plated?

Is it gold vermeil?

Does it contain pearls, mother of pearl or other materials that require additional care?

Those details tell you far more about the construction of the jewellery than the words “gold-plated” alone.
