Rhodium Plating: Why White Gold Goes Dull (and What to Do)

White gold does not stay the bright white it is when new. Over a year or a few, the surface dulls towards a warmer tone, and people often wonder whether the ring has been damaged or whether they were sold something lesser. Neither is true. What has happened is that a thin plating has worn, and the fix is as simple as the cause.

Why white gold is plated at all

Gold is yellow. To make white gold, it is alloyed with white metals, which lightens the colour but does not make it colourless. So a white gold piece is finished with a plating of rhodium, a hard, bright-white metal, which gives it the crisp white surface people picture when they picture white gold.

The plating is a finish rather than the body of the ring. The metal underneath is white gold, and it is sound.

Why it dulls

Rhodium plating is thin, and it wears. Friction against a neighbouring ring, hand washing, cleaning products and everyday contact all take their toll, and the plating thins unevenly as they do. As it thins, the warmer tone of the gold beneath begins to show through, and the surface loses the brightness it had when it was new.

So the dullness is not dirt and it is not damage. It is the finish wearing away, exactly as a finish is expected to.

How often it needs doing

Rhodium re-plating is needed every one to three years. That is craft guidance rather than a promise, and the interval varies with how and where a ring is worn. A ring worn daily and stacked against others will need it sooner; one worn occasionally will need it later. There is no schedule to keep to for its own sake. The right time is when the finish has worn enough to bother you.

What it is not

A few things are worth saying plainly, because they are commonly muddled:

• It is not damage. The metal itself is unaffected. Worn plating is a surface finish, and a surface finish can be renewed.
• It is not a fault in the ring. Every rhodium-plated piece does this, in time. It is a property of the finish, not of your particular ring.
• It is not a sign you were sold something second-rate. White gold is white gold. The plating is how it is finished, not a trick.

What to do about it

Re-plating restores the finish. It is a small, quick piece of workshop work, and it leaves the ring looking as it did when it was new. If you are not sure whether your ring needs it or simply needs cleaning, bring it in and we will tell you which. The two look similar at a glance and are easily confused.

If cleaning is all that is needed, it is worth knowing how to do it safely; our guide to caring for your jewellery covers that. And if the worn finish has prompted a larger question about metals, that is a good conversation to have properly rather than by guesswork.

Frequently asked questions

How long does rhodium plating last?

One to three years, as a guide. It depends on how often the ring is worn and what it meets day to day.

Does rhodium plating damage the gold underneath?

No. The gold is untouched. Only the thin surface plating changes, and renewing it is straightforward.

Can I tell whether my ring needs re-plating or just cleaning?

Not always by eye. Dullness from worn plating looks much like dullness from grime at first glance. Bring it in and we will tell you which yours needs.

Will re-plating change my ring?

No. It restores the bright finish it had when new. The ring itself is unchanged.
