Rhodium Plating Guide — What It Is and When to Re-Plate
Share
If you own white gold jewelry, you've probably encountered the term "rhodium plating." Understanding what rhodium plating is, why it matters, and when to have it done will help you keep your white gold looking its best. Here's everything you need to know.
What Is Rhodium?
Rhodium is a precious metal in the platinum group, known for its exceptional hardness, reflectivity, and brilliant white color. It's actually rarer and more valuable than gold or platinum. In jewelry, rhodium is applied as an ultra-thin layer on white gold to enhance its white color and add a protective coating.
Why Is White Gold Rhodium-Plated?
Here's the thing: white gold isn't naturally brilliant white. It's yellow gold alloyed with white metals (like palladium or nickel), which gives it a light gray or slightly yellow appearance. Rhodium plating is applied to give white gold that classic, bright, platinum-like white finish that most buyers expect.
How Is Rhodium Plating Applied?
Rhodium plating is an electroplating process. The jewelry is thoroughly cleaned, then submerged in a solution containing dissolved rhodium. An electric current causes the rhodium to bond to the metal surface in an ultra-thin layer (typically 0.5-1.5 microns). The process takes only minutes and leaves the piece with a brilliant, high-polish finish.
How Long Does Rhodium Plating Last?
Rhodium plating wears down over time with daily wear. How quickly depends on:
- How often and how hard the piece is worn
- Exposure to chemicals (lotions, perfumes, cleaning products)
- The thickness of the original plating
- The wearer's skin chemistry
For engagement rings and wedding bands worn daily, rhodium plating typically lasts 1-2 years before touch-up is needed.
Signs It's Time to Re-Plate
- The ring appears yellowish or grayish in color
- The finish looks dull rather than bright and reflective
- You can see the underlying yellow gold color showing through, especially on the edges
