What Is Rhodium Plating and Why Does Your White Gold Need It?

The Secret Behind White Gold's Brilliance

If you own a white gold ring, you may have noticed it can gradually take on a slightly warm or yellowish tone over time. This is completely normal — and it is why rhodium plating exists. At Corelune Jewellery, we want you to fully understand the jewellery you own, including why white gold is treated with rhodium.

What Is White Gold?

Pure gold is inherently yellow. White gold is created by alloying yellow gold with white metals — typically palladium, silver, nickel, or manganese. The resulting alloy is naturally a pale, slightly warm grey-white colour. To achieve the bright, mirror-white appearance that white gold is famous for, the surface is coated with a thin layer of rhodium.

What Is Rhodium?

Rhodium is a rare, precious metal belonging to the platinum group. It is extraordinarily hard, highly reflective, and completely resistant to tarnish and corrosion. When applied to white gold, rhodium provides a brilliant, pure white surface and adds a protective layer that helps resist scratching.

How Long Does Rhodium Plating Last?

Rhodium plating is not permanent. Over time — typically one to three years for a ring worn daily — the rhodium layer gradually wears away, particularly at the highest points of contact. As it wears, the underlying yellow-white colour of the gold alloy begins to show through. The rate of wear depends on how often the piece is worn, the wearer's skin chemistry, and exposure to chemicals.

When Should You Have Your White Gold Replated?

When you notice your white gold starting to look warm or yellow, it is time to have it replated. This is a straightforward process — a jeweller will clean the piece, polish it to remove any scratches, and apply a fresh rhodium coating. At Corelune Jewellery, we offer professional rhodium replating as part of our jewellery maintenance services.

Is Rhodium Plating Only for White Gold?

No — rhodium can also be applied to sterling silver to give it a bright, tarnish-resistant surface, and occasionally to yellow gold for a distinctive white contrast effect in two-tone jewellery designs.
