What is rhodium-plated white gold?
Rhodium-plated white gold is a gold alloy covered with a thin layer of rhodium to give it a brilliant white color.
Why is white gold rhodium plated?
In its natural state, gold is yellow. To obtain white gold, jewelers mix pure gold with other whitening metals such as silver or palladium. However, this alloy often retains a slight grayish or pale yellow tint. This is where rhodium comes in, a very rare and particularly hard precious metal from the platinum family.
The application of this electroplated coating:
- Gives the jewelry a bright white luster, very similar to that of platinum.
- Creates a hypoallergenic barrier between the skin and the other components of the alloy.
How does this metal change over time?
It's important to note that rhodium plating is not permanent. As it is a surface treatment, the layer of rhodium eventually wears away due to repeated friction, gradually revealing the natural, slightly warmer hue of the white gold underneath. This phenomenon is completely normal and does not mean your jewelry is of poor quality.
The speed of this wear depends on the acidity of the skin and how often the jewelry is worn. A ring worn daily, such as one of our engagement rings, will require more regular maintenance than a pendant. To restore its original shine, simply entrust your piece to a jewelry workshop for a new rhodium plating.
What are the differences with platinum?
Although visually very similar when new, rhodium-plated white gold and platinum are two distinct materials. Platinum is naturally white and requires no plating; it will retain its color indefinitely, although it may develop a patina over time. Rhodium-plated white gold, on the other hand, is lighter and offers a brighter shine thanks to the rhodium, but requires periodic maintenance to maintain its "mirror white" hue.
The choice between the two often depends on budget and preference for the weight of the jewelry. White gold remains a preferred option for its versatility, particularly in the creation of white gold necklaces and pendants or men's wedding bands. In fact, many models in our collection of men's wedding rings use this metal for its contemporary and refined aesthetic.
Frequently Asked Questions About Rhodium-Plated White Gold
No, rhodium-plated white gold does not tarnish like silver, which oxidizes. However, when the rhodium layer wears off, the jewelry may take on a slightly yellowish tint, which is the natural color of the gold alloy beneath the plating.
Yes, you can wear your jewelry underwater, but it is advisable to avoid chemicals, chlorine from swimming pools, and harsh household products. These substances can accelerate the wear of the rhodium layer and dull the jewelry's shine.
The lifespan of rhodium plating generally ranges from 1 to 3 years for a ring worn daily. For earrings or pendants that experience less friction, the plating can remain intact much longer, sometimes several years.
