Why is Rose Gold Plating Funky? Could it be the Copper?

Rose gold Plated Chains. It May be a Fine Layer, but They Look Real.

Melia’s Spotty Rose Gold Plating

Melia bought a discolored rose gold plated pendant at a sale. She figured she’d just polish it up. She tried various silver and copper polishes and only succeeded in pulling most of the rose plating off and leaving it splotchy looking. Melia was not happy.

I got the call, “can you re-plate my rose gold plated pendant?”

Me: “Most likely. It is problematic however.”

Melia: “How come?”

Me: “To create the rose gold plating solution, a lot of copper is used, just like in the creation of rose gold itself. And copper has problems.”

Melia: “Like darkening?”

Me: “Yup.”

Melia: “You should see it after I cleaned and polished it with copper cleaner.”

Me: “Pretty bad?”

Melia: “Superbad. So if I have you plate it can you do it super deep so it’ll last longer and not turn dark?”

Me: “Not really. I mean I can rose gold plate your pendant, but rose gold plating wears off faster than yellow gold plating or rhodium white plating. And if rose gold plating is exposed to certain chemicals it can darken. Usually just in a spot here or there, making it look especially bad.”

Melia: “Wow you’re really sellin’ it.”

Me: “It’s my superpower.”

Melia: “I just want something to wear everyday that is rose gold. What would make it look nice?”

Me: “Some people who make costume jewelry and rose gold plate it also put on what they call an e-coat, which supposedly creates a barrier protecting the plating longer. I don’t offer that service.”

Melia: “So my friend Anita has a rose gold plated Michael Kors watch she’s had for a while and it’s gotten dark on the back. It does not look good. Do you think it is e-coated?”

Me: “Good chance of it.”

Melia: “How about you rose gold plate my pendant and we’ll just see how long the plating lasts?”

Me: “I can do that!”

One Year Later

We ended up plating her pendant with white rhodium and it’s looking great.

Melia had me design a rose gold ring in 14kt karat. She’s loving it and the rose gold is behaving quite well, now that it’s not plated rose gold.

  1. I love the Rose platted chain with the information . Copper is so much useful in the creation of this gold chain.

  2. Hello! I recieved a beautiful engagement ring from my fiance that rose gold rhodium plating over sterling silver with artificial diamond stones. After 1 night of wear, the rose gold color was coming off leaving the sterling. I love the ring dearly and don’t want to part with it, so I am wondering if the rose gold color cam be restored or just removed to be left with the silver? I’d be happy to send pictures to see what you think our options are!

    • Hello Sara,
      Even if you re-plate it it’ll probably happen again. I’m guessing your best option is to remove the plating and wear it as just silver.
