Rhodium Plating Explained: Why White Gold Needs a Refresh
White gold rings start bright white and slowly turn warmer. That is rhodium plating wearing off, not a fault. How plating works, how long it lasts and when to refresh it.
If your white gold ring looks a little warmer than the day you bought it, nothing is wrong. White gold is almost always rhodium plated for its bright, cool finish, and that plating wears gradually with daily life. Here is how it works, how long it lasts and how to refresh it.
Why white gold is plated
Gold is naturally yellow. White gold is made by alloying gold with whiter metals such as palladium, silver or nickel, but the result is usually a soft, slightly creamy grey rather than pure white. To give it the bright, mirror-white look people expect, jewellers electroplate the finished piece with a microscopically thin layer of rhodium, a rare, hard and highly reflective metal of the platinum family.
How long does rhodium plating last?
It depends on how much friction the piece gets. On an engagement ring worn every day, the palm side can start to show wear within a year or so; with gentle wear it can last several years. Earrings and pendants, which rub against very little, can stay bright for many years.
| Piece | Typical time before replating |
|---|---|
| Ring worn daily | 1–2 years |
| Ring worn occasionally | 3–5 years |
| Bracelet | 2–3 years |
| Earrings and pendants | Many years |
What replating involves
- Inspection: the jeweller checks prongs and stones first, so any repairs happen before plating.
- Cleaning and polishing: scratches are polished out and the surface is degreased completely.
- Plating: the ring is dipped in a rhodium solution with an electric current for a short time.
- Finishing: it is rinsed, dried and checked. The whole job usually takes an afternoon.
Making the finish last longer
- Take rings off for the gym, cleaning and gardening.
- Avoid chlorine, harsh chemicals and abrasive cleaners.
- Store pieces separately so diamonds cannot scratch the plating.
- Clean gently with warm water, mild soap and a soft brush.
White gold, yellow gold or rose gold?
If you would rather never think about plating, choose yellow or rose gold, whose colour runs right through the metal. Sterling silver is sometimes rhodium plated too, to slow tarnishing. Our white gold pieces leave the workshop freshly plated, and our care guide covers looking after every metal we use.
Signs it is time to replate
- A warm, yellowish tint on the palm side of the band, where it rubs most.
- A visible difference in colour between the band and the prongs.
- A finish that still looks dull after a thorough clean.
- Your skin reacting to a ring it never bothered before.
Rhodium and sensitive skin
Rhodium itself is very unlikely to cause a skin reaction, and the plating acts as a barrier between your skin and the alloy underneath. Some white gold alloys contain nickel, a common allergen. When the plating wears through, people sensitive to nickel may notice itching or redness where the ring sits. Replating solves it for a while; choosing a nickel-free (palladium) white gold, or yellow or rose gold, solves it for good.
White gold or platinum?
White gold
- Bright, mirror-white finish when plated
- Lighter and more affordable
- Same alloy family as your other gold pieces
Things to know
- Needs replating every few years
- Platinum is naturally white with no plating
- Platinum is heavier, denser and costs more
White gold, freshly plated
Is white gold turning yellow a defect?
No. It is the rhodium plating wearing away to show the natural, slightly warmer colour of the alloy underneath. Replating restores it.
Does replating damage the ring?
No. Plating adds a microscopically thin layer; the polishing beforehand removes only a tiny amount of metal.
Can rose or yellow gold be rhodium plated?
It can, to make it white, but most people choose those golds for their natural colour.
How thick is rhodium plating?
Very thin: typically well under a thousandth of a millimetre. That is enough for a brilliant finish, but it is why plating wears over time.
Is rhodium plating good for sensitive skin?
Yes. Rhodium rarely causes reactions and shields skin from the alloy underneath while the plating is intact.
