Does White Gold Tarnish? Rhodium Plating and Re-Plating Explained
If you have noticed your bright white engagement ring slowly taking on a dull, yellowish hue, you might worry that your precious jewellery is ruined or made of poor materials. A common question for many UK buyers is: does white gold tarnish over time? Discovering the truth about how this metal behaves is key to keeping your favourite pieces looking as bright as the day you first put them on.
Does white gold tarnish like silver or copper?
No, white gold does not tarnish in the traditional sense of oxidisation, but its outer rhodium plating wears away to reveal the warm, yellowish-white natural gold alloy underneath. Unlike sterling silver or copper, which react with sulfur and oxygen in the air to form a dark, dull layer of tarnish, gold is a noble metal that does not oxidise. However, because pure gold is naturally rich yellow, jewellers must mix it with white metals such as palladium, silver, or manganese to create a white gold alloy. This alloy still retains a subtle, warm champagne-yellow tint, which is why almost all commercial white gold jewellery is electroplated with a micro-thin layer of rhodium. To understand how white gold compares to other warm-toned metals, you can read our comparison on rose gold vs yellow gold vs white gold.
What causes white gold to change colour over time?
The primary cause of white gold changing colour is friction and chemical exposure wearing down the thin layer of rhodium plating on the surface of the metal. Every time your ring rubs against your skin, touches hard surfaces, or comes into contact with everyday household chemicals, a tiny amount of the rhodium plating is rubbed away. Over a period of months or years, this constant abrasion exposes the natural, warm-toned white gold beneath. This transition is not a chemical reaction or a defect in the metal; it is simply physical wear and tear. If you prefer a metal that is naturally bright white and does not require plating to maintain its colour, you might want to explore our guide on white gold vs platinum engagement rings.
What is rhodium plating and why is it used?
Rhodium plating is a process where a micro-thin layer of rhodium—a highly reflective, scratch-resistant metal from the platinum family—is electroplated onto white gold to give it a bright, mirror-like white finish. Rhodium is one of the rarest and most expensive precious metals on earth, valued for its incredible hardness and brilliant silvery-white lustre. Because white gold alloys are naturally slightly dull or yellowish, a layer of rhodium measuring between 0.75 and 1.5 microns thick is applied to provide that signature high-shine, ice-white look. This plating also provides a temporary barrier against minor surface scratches, protecting the softer gold alloy underneath. Every piece of white gold jewellery we produce in our Türkiye workshop is finished with a high-quality rhodium plating layer to ensure a premium, bright white appearance from day one.
How often do you need to re-plate white gold jewellery?
Most people need to re-plate their white gold jewellery every 12 to 24 months, depending on how often the piece is worn and the wearer's skin chemistry. Rings that are worn daily, such as engagement rings and wedding bands, experience constant contact with hard surfaces, soaps, and skin oils, meaning they will require re-plating much sooner than earrings or necklaces. Some individuals have more acidic skin oils, which can accelerate the wear of the rhodium layer, requiring re-plating every 6 to 9 months. In contrast, a pair of white gold earrings worn occasionally might retain its bright rhodium finish for a decade or more without needing any maintenance. The cost of having a local manufacturing jeweller re-plate a standard ring in the UK typically ranges between £30 and £80, depending on the thickness of the plating and the complexity of the design.
Does 9ct white gold tarnish faster than 18ct white gold?
While neither metal oxidises like sterling silver, 18ct white gold contains more pure yellow gold (75%) than 9ct white gold (37.5%), meaning the underlying metal of an 18ct ring will appear noticeably more yellow once the rhodium plating wears thin. Because 9ct gold is alloyed with a higher percentage of white metals like silver and palladium, its natural, unplated state has a slightly lighter, more muted champagne tint compared to the richer, warmer yellow-champagne hue of unplated 18ct gold. When the rhodium plating inevitably wears away, the colour contrast on an 18ct white gold ring is often more pronounced. When deciding between 9ct and 18ct, understanding how and why does white gold tarnish or change colour helps you make an informed decision about your purchase. To verify the purity of your metal, every piece from Qutahia is stamped with its gold fineness mark (375 for 9ct, 585 for 14ct, or 750 for 18ct) in our workshop before dispatch. If you are concerned about skin sensitivity when the plating wears down, you can learn more by reading our article on is 9ct gold hypoallergenic and nickel allergy in the UK, noting that all Qutahia pieces are produced in accordance with REACH nickel-release standards.
How can you prevent white gold from turning yellow?
You can delay white gold from showing its underlying yellow hue by removing your jewellery during heavy cleaning, avoiding contact with harsh chemicals like chlorine, and keeping it dry. Chlorine in swimming pools and hot tubs is particularly damaging, as it can actually attack the gold alloys beneath the plating, causing stress corrosion cracking over time. Household cleaning products, hand sanitisers, perfumes, and lotions also contain chemical compounds that accelerate the erosion of the protective rhodium layer. By taking your rings off before washing your hands, applying skincare products, or doing the washing up, you can significantly extend the lifespan of your rhodium plating. Additionally, storing your jewellery in a soft, fabric-lined box away from other pieces will prevent abrasive scratches that wear down the plating.
What is the process of re-plating white gold?
The process of re-plating white gold involves stripping any remaining rhodium, polishing the metal to remove scratches, cleaning it thoroughly in an ultrasonic bath, and then electroplating a fresh layer of rhodium onto the surface. First, the jeweller must polish the ring to a high shine because rhodium will not mask existing scratches; it will only highlight them. Once the piece is perfectly smooth and chemically clean, it is dipped into a heated bath containing rhodium sulphate and other chemicals. An electric current is passed through the solution, causing the rhodium ions to bond securely to the surface of the gold. This entire process is highly straightforward but requires professional equipment to ensure the plating is even, durable, and free from dark spots or peeling.
Frequently Asked Questions
Does white gold tarnish if you wear it every day?
Yes, white gold will gradually lose its bright white lustre and show its natural warm undertone if worn daily, as constant friction wears away the protective rhodium plating. This is a natural physical process rather than chemical tarnishing, and it can be easily resolved by having the piece re-plated every one to two years.
Can you wear white gold in the shower?
Yes, you can wear white gold in the shower, but the soaps, body washes, and hard water minerals will build up on the surface and accelerate the wear of the rhodium plating. To keep your ring looking bright and clean for as long as possible, we recommend removing it before bathing.
Is white gold hypoallergenic?
Yes, white gold can be hypoallergenic, but this depends on the specific alloys used by the manufacturer. All Qutahia jewellery pieces are produced in accordance with REACH nickel-release standards, ensuring they are safe for sensitive skin and comply fully with European and UK safety regulations.
How much does it cost to re-plate a white gold ring in the UK?
The cost to professionally polish and re-plate a white gold ring in the UK typically ranges between £30 and £80. This price depends on the width of the band, the complexity of the stone settings, and whether the jeweller needs to perform any minor repairs before plating.
Does white gold turn your finger green?
No, genuine white gold will not turn your finger green. Green skin discolouration is caused by cheap base metals like copper reacting with your skin acids, whereas high-quality gold stamped with its fineness mark (375, 585, or 750) does not cause this reaction.
What is the difference between white gold and platinum?
The main difference is that platinum is a naturally white metal that never changes colour or requires plating, whereas white gold is a yellow gold alloy that relies on rhodium plating to achieve its bright white finish. Platinum is also denser and heavier, but white gold is generally harder and more scratch-resistant.
How long does the rhodium plating process take?
The actual electroplating process takes only a few minutes, but the preparation, polishing, and cleaning of the jewellery usually require a local workshop to hold the piece for a few hours to a couple of days.
How long does a custom white gold ring take to make?
Our standard making time is 10-14 days for simpler designs (solitaire, classic pavé) and 4-6 weeks for more complex commissions (intricate settings, less common stone shapes/sizes, fully bespoke designs), plus separate postage time on top of either. This tiered timeline ensures our workshop in Türkiye can dedicate the necessary time to cast, clean, and hand-set each unique piece.
How does Qutahia guarantee the quality of its white gold jewellery?
