How often does white gold need to be replated with rhodium?

Every twelve to eighteen months. That's the schedule I give clients for a daily-wear white gold ring, and I'd rather say that up front than pretend the plating is permanent. For a ring worn occasionally, you might get three or four years between rhodium replating. For a wedding band worn during gym sessions, dishwashing, and sleep, eight months wouldn't shock me.

Rhodium is a platinum-family metal that gets electroplated over white gold in a thin layer, usually 0.1 to 0.5 microns, and it's hard but it's also just a coating that wears off to reveal the alloy underneath. That alloy is a warm, slightly grey or yellowish white. 14k white gold has more nickel and can look more yellow once the rhodium goes. 18k white gold with palladium is greyer underneath but still not the bright chrome white most clients expect.

What controls the timing

Body chemistry is the variable I can't predict. Some clients get a full year or more. Some, like a client named Priya last spring, walk in after seven months with a band that looks almost yellow at the edges. That's just skin oils, sweat, and maybe a bit of hand lotion. She wasn't doing anything wrong.

Friction is the second thing. The back of the band, the prong tips, and the area under the head lose rhodium first. If you wear another ring next to it, the contact points strip faster. A ring that slides against a platinum or gold band daily will need replating sooner than one worn alone.

When to replate and when to wait

I tell clients to look at the back of the band and the prongs. If those areas turn noticeably warm or yellow, the rhodium is gone there. You don't have to replate immediately. The ring isn't damaged. Some clients actually like the warmer white look and skip replating for years, which is fine as long as they know they're seeing the alloy, not a defect.

But if you bought white gold specifically because you want that bright, cool white, plan on every twelve to eighteen months, and expect to pay around $60 to $120 for a proper job. That should include a light polish, cleaning, and replating. If a jeweler quotes much less, ask if they strip the old rhodium first. Some shops just plate over hand lotion and old rhodium, and that's why the new plating peels in a month.

I also tell clients not to over-polish before replating. Each polish removes a tiny amount of gold. Over twenty years, an aggressive polish twice a year will thin a shank enough that I'd refuse to resize it. Replate when the color bothers you, not on a calendar.

One last thing. If you're nickel-sensitive, the rhodium layer is doing real work as a barrier. Don't wait until the ring turns yellow and starts irritating your skin. At that point the nickel in 14k white gold is exposed, and that becomes a different conversation. I'd rather replate early for allergic clients than have them wearing a ring that burns a red band into their finger.
