Rose Gold Never Needs Replating. White Gold Does.

Rhodium replating white gold is routine upkeep: a ring worn every day needs it roughly every one to three years, and UK jewellers commonly charge £40 to £75 for a plain band. Rose gold never needs it at all. Its colour comes from copper alloyed through the whole metal, so there is no surface layer left to wear away.

That is the short version. The longer one matters, because most people buy a white gold ring without ever being told it has a consumable part.

What is rhodium, and why is it on your white gold ring?

Rhodium is a silver-white metal from the platinum group, applied to jewellery as an electroplated layer a fraction of a micron thick. It does not tarnish and it does not corrode. Reference tables usually put it around 6 on the Mohs scale, harder than the gold underneath, and it throws back light in a way gold alloys simply cannot. On a finished ring it reads as cold, bright, near-mirror white.

It is there because white gold is not white. Gold is yellow, and no amount of alloying fully argues with that. Refiners mix it with whitening metals — usually palladium or nickel, plus silver and a little zinc — and the result is paler than yellow gold but nowhere near the colour most people picture when they hear the words. So the finished piece is dipped.

The layer is thin on purpose. General trade practice puts it at roughly 0.75 to 1.0 microns on most jewellery, and sometimes up to about 1.5 microns on rings, which take the roughest treatment. Go thinner and the alloy shows through almost immediately. Go thicker and the plating turns brittle and starts to craze. There is not much room to play with.

How often does white gold need rhodium replating?

One to three years is the range most jewellers quote for an engagement ring worn daily, with a common suggestion to have it looked at somewhere around the 18 to 24 month mark. If you work with your hands, garden without gloves, or wear a wedding band pressed tight against a solitaire so the two rub all day, six to twelve months is closer to the truth.

Earrings and pendants are a different case entirely. They barely touch anything. A plated pendant can hold its finish for years on end, because what removes rhodium is friction, not time. Two people can buy identical pieces on the same afternoon and have completely different experiences of them.

It also does not wear evenly, which catches people out. The plating goes first at the points of contact — the palm side of the shank, the outer edges of the setting, the tops of the claws, the shoulders where a second ring sits against it. You end up with a ring that is still bright white when you look straight down at it and noticeably warmer underneath. Most people notice it as a slight dullness before they notice it as a colour.

What does rhodium replating white gold cost in 2026?

The figures below are general trade ranges quoted by jewellers and repair workshops as of August 2026. They are not our prices. Rhodium itself is expensive — Umicore's published indication for 21 August 2026 put it at €262,300 per kilogramme — but barely any of it goes onto a ring. The labour and the polishing are what you are paying for.

Replated every two years at £55, a ring costs about £825 across a thirty-year marriage — spread thinly enough that nobody feels it. Worth knowing before you commit, all the same.

What does unplated white gold actually look like?

Warm and faintly grey, is the honest answer. Not yellow, whatever the internet says. Palladium-based white gold, left unplated, is a soft dull grey somewhere near a matte platinum. Nickel-based white gold is paler and slightly steelier. Both are handsome metals. Neither is the cold reflective white of a fresh rhodium dip.

When someone says their white gold ring "turned yellow", they usually mean it warmed up — moved from a hard white to a soft champagne-grey. Next to a freshly plated ring that shift looks dramatic. On its own, most people would not think twice. A small but real group of jewellers argue against plating white gold at all, on the grounds that the maintenance cycle is a problem the trade invented for itself. Not an unreasonable position.

The part nobody mentions: what repeated replating does to a ring

Plating cannot go onto a dirty or scratched surface, so before a ring goes in the bath it is cleaned and polished. Polishing removes metal. Only a trace each time, but the trace is real, and it comes off the places that already carry the least material — claw tips, engraved edges, millegrain beading, the fine walls of a pavé setting. One replate is nothing. Fifteen of them, across a few decades, is how a claw quietly becomes a stub.

Stones complicate it further. Pearls, opals, turquoise and coral cannot go through the heat and chemistry of an electroplating bath at all, and are either masked with great care or removed and reset afterwards. Emeralds, which are commonly oil- or resin-treated, get the same caution. Diamonds are unbothered, which is one reason a plain diamond ring sits at the cheap end of every replating price list.

There is a skin-contact angle too. Under the EU's REACH regulation, Annex XVII entry 27 — the rule that replaced the old Nickel Directive 94/27/EC, and which the UK retained after Brexit — items in prolonged contact with skin must not release more than 0.5 micrograms of nickel per square centimetre per week. Compliant nickel white gold is legal and widely sold. But fresh rhodium also happens to sit between skin and alloy, and as it wears that barrier thins with it. If nickel is a concern for you, a palladium-based white gold removes the question rather than covering it.

Why does rose gold never need any of this?

Because the colour is not a coating. 18K rose gold is 75% gold by definition, with the remaining quarter made up of roughly 22 to 23% copper and a little silver; 14K is 58.3% gold with a good deal more copper again, which is exactly why 14K rose reads pinker than 18K does. The copper goes into the melt. It is distributed through the entire body of the metal, so a cross-section of a rose gold band is the same colour as its surface.

Nothing can wear through, because nothing is on top. A rose gold ring worn for thirty years will scratch, soften at the edges and pick up the fine web of marks that any daily-worn ring collects. Copper does oxidise slowly at the surface, so some pieces deepen very slightly over the years — a change most owners like. A polish takes it back. No bath, no appointment, no interval. The same logic applies to yellow gold, for the same reason.

So which should you choose?

Choose white gold if you genuinely want that hard, cool white. Nothing else delivers it at the price, and the upkeep is a known quantity rather than a nasty surprise — closer to servicing a watch than to fixing a fault. If you go this way, choose a setting with substantial claws rather than the finest possible ones, since those are what the polishing wheel eats first. Our white gold collection is where to start if that is the look you are after.

Choose rose gold if the idea of a standing maintenance appointment quietly annoys you, or if the ring is going onto a hand that does real work. Copper also makes it a touch harder than yellow gold, which does no harm on a piece of everyday gold.

And if what you actually want is white metal with no plating cycle at all, the honest options are an unplated palladium white gold, or platinum — a different metal at a different price, but one that is white the whole way through. Karat choice matters here as well, since it changes both colour and hardness; we have written separately about what the karat numbers actually mean.

Every Signora piece is made to order at our own bench in Surat, so the metal is chosen when the ring is commissioned rather than picked off a shelf. Everything we make is solid 9 to 18K gold — never vermeil, never plated base metal — so whatever finish sits on the surface, the gold underneath goes all the way down. If you are still deciding, our engagement ring guide covers metal, setting and stone together, and the solitaire rings are a good place to see the two metals side by side. We would far rather talk you into the metal that suits your hands than the one that photographs best.
