Everything you need to know about White Gold & Rhodium Plating

If you've ever noticed your white gold ring starting to look a little dull or slightly yellow, you’re not imagining things and it doesn’t mean your jewellery is faulty. It just means it might be time for a refresh. In this guide, we’ll walk you through what rhodium plating is, why it's used, and how to know when it's time for a touch-up

What Is White Gold?

Here’s the truth: white gold doesn't exist! At least not naturally...

White gold is made by mixing pure 24k yellow gold with other white metals such as palladium or silver. This mix, called an alloy, lightens the colour of the gold, giving it a pale, silvery hue. But even after alloying, white gold still has a slightly grey or yellowish tint, depending on the alloy mix. That’s why most white gold jewellery is coated with rhodium to give it that bright white finish we love. 

Does White Gold Tarnish?

White gold doesn’t tarnish, but the rhodium plating does fade. As you wear your ring daily, the plating slowly wears off, revealing the slightly warmer tone of the underlying metal.

To keep your white gold looking its best, you’ll need to have it replated every 1–3 years, depending on your lifestyle and how often you wear the piece.

What Is Rhodium Plating?

Rhodium is a rare, naturally white metal from the platinum family. However, it's too brittle to be made into jewellery on its own, so instead, it’s used as a plating layer over other metals; most commonly white gold.

How Long Does Rhodium Plating Last?

On average, it can last between 12 to 36 months, depending on how often you wear the piece. Rings usually require more frequent replating since they’re exposed to everyday activities like handwashing, typing, and even moisturising. Necklaces and earrings tend to hold their plating a lot longer.

And don’t worry, it’s a totally normal part of jewellery maintenance, just like getting your car serviced or polishing your favourite boots. A quick replate can make your piece look brand new again.

Signs It Might Be Time to Replate Your Jewellery

Not sure if your white gold needs replating? Here are some signs to watch for:

✨ Dullness or Yellowing – If your white gold starts to look slightly warm or yellowish, the rhodium may have worn off.

✨ Uneven Colour – Often seen on rings, particularly underneath where it rubs against surfaces.

If you notice either of these, it might be time to pop in and see your jeweller for a quick refresh (and yes, we’d love to help!).

Benefits of Rhodium Plating

Rhodium plating isn’t just about looks - it brings some serious benefits that help your jewellery last longer and stay beautiful:

• Durability – Rhodium is extremely hard, adding a protective layer that resists scratches and everyday wear.

• Enhanced Appearance – It gives your jewellery a bright, reflective, mirror-like finish that makes diamonds and gemstones pop.

• Tarnish Resistance – Unlike silver or unplated white gold, rhodium doesn’t tarnish, keeping your pieces looking fresh and clean.

• Hypoallergenic – Rhodium is nickel-free and skin-friendly, making it ideal for those with sensitive skin or metal allergies.

How to Clean Rhodium-Plated Jewellery

For everyday cleaning at home, we recommend using a mild soap mixed with warm water. Soak your piece for a few minutes, then gently wipe it down with a soft cloth or microfiber towel. Rinse thoroughly and pat dry with a lint-free cloth.

The key here? No harsh chemicals or abrasive scrubbing. Avoid jewellery cleaners that contain ammonia or alcohol, and hard brushes - these can cause the rhodium to wear down more quickly.

If your piece needs a deeper clean or has lost its shine, it’s best to bring it to a professional jeweller for a safe and thorough clean.

And don’t forget about storage: keeping your jewellery in a soft pouch or a separate compartment in your jewellery box helps prevent scratching and keeps that gorgeous finish intact for longer.

White Gold vs Platinum: What’s the Difference?

White gold and platinum look very similar but they’re quite different in composition, cost, and maintenance.

If you love the look of white metal but want less maintenance, platinum could be a better fit - especially for engagement or wedding rings worn daily.
