That stunning white gold jewellery piece you love? Over time, it might surprise you by showing a faint yellowish tinge. Not exactly the look you signed up for, right? Keep reading to understand why white gold colour changes over time, what causes it and the best ways to keep that gorgeous white glow going strong.
What Is White Gold?
Despite its name, white gold isn’t purely white. It is an alloy, typically made by mixing yellow gold with metals like palladium, silver or nickel. This mix creates a metal that’s lighter than traditional yellow gold but still durable. To give it that bright, lustrous look, white gold jewellery is then coated with rhodium, a silvery-white metal that not only boosts shine but also adds to its strength.
However, as with any coating, rhodium doesn’t last forever. Over time, this rhodium layer can wear off, and that’s when you start to notice changes in the colour of your white gold jewellery piece.
Why Does White Gold Turn Yellow Over Time?
The key reason for colour changes in white gold is the natural wearing away of its rhodium coating. Here’s what happens:
1. Everyday Wear and Tear: Just like the soles of your favourite shoes, the rhodium coating on white gold jewellery piece experiences gradual wear, especially if it’s a ring or bracelet that’s exposed to a lot of friction. As this coating wears away, the underlying metal—usually a light yellow or greyish colour—begins to show through, causing your jewellery to look less white.
2. Exposure to Elements: Skin oil, lotions, perfumes and even the minerals in water can contribute to the gradual breakdown of the rhodium layer. Over time, these elements subtly dull the shine and whiteness of white gold, making it appear darker or slightly yellowish.
3. Natural Composition of White Gold: Because white gold contains yellow gold, it’ll always have a warm undertone beneath that rhodium coating. Once the rhodium layer thins, the natural tint of the gold alloy becomes more visible.
Can You Restore White Gold to Its Original Shine?
Absolutely! Unlike other metals, white gold’s appearance can be refreshed with a process called rhodium plating or rhodium dipping. This involves applying a new layer of rhodium to the jewellery piece. This not only restores its bright, silvery-white finish but also adds a protective coating. Your jeweller will first thoroughly clean the piece to remove any oil or residues. Then, using a rhodium solution, they’ll plate the jewellery with a fresh layer of rhodium. This entire process typically takes only a few hours and can make your jewellery look as good as new.
For most people, rhodium plating lasts around one to two years. However, this depends on how often you wear the jewellery piece. Rings may need more frequent plating since they experience the most friction, while necklaces and earrings might last longer between treatments.

Common Myths About White Gold Colour Changes
There are a lot of myths floating around about white gold and why its colour changes over time. Let’s set the record straight on a few of them:
1. White gold isn’t real gold
Wondering whether white gold is real? Well, white gold is real gold, just alloyed with other metals to achieve its colour and durability. The ‘white’ part comes from the metals it’s mixed with, plus that rhodium coating over it.
2. White gold that turns yellow is fake
White gold with a yellow tint isn’t fake. In fact, a slightly yellowish tint is normal as the rhodium wears off, revealing the gold alloy beneath. A quick rhodium re-plating can restore its original colour.
3. White gold should look the same forever
Just like any other metal, white gold requires a bit of maintenance to keep it looking fresh. Rhodium plating won’t last forever, and that’s completely normal for white gold jewellery.
How to Care for White Gold Jewellery
If you want to extend the lifespan of that gorgeous white finish, here are a few simple tips to help with white gold maintenance:
1. Limit Exposure to Chemicals: Chemicals in perfumes, lotions, and cleaning products can wear down rhodium faster. Put your jewellery on after applying personal care products and avoid exposing it to harsh cleaning agents.
2. Avoid Chlorine and Salt Water: Chlorine, especially in pools or hot tubs, can be particularly harsh on white gold. If you’re planning to take a dip, it’s a good idea to take off your jewellery.
3. White Gold Cleaning: Gently clean your white gold jewellery with a soft cloth or a mild soap and water solution. Avoid abrasive cleaners or brushes, as they can scratch the surface and wear down the rhodium layer.
4. Consider Regular Cheque-Ups: If you wear your white gold jewellery daily, it’s a good idea to have it chequeed and cleaned by a jeweller once or twice a year. They can tell you when it’s time for fresh rhodium plating.
