"Protect mother of pearl for gold or rhodium plating?"
Current question:November 17, 2021
I know it is old subject, but what can I use as a clear coat to protect mother of pearl when gold plating?

Q. I have a pair of medical insignia mother of pearl cufflinks on which the edges and the insignia are made from yellow gold. I am not much of a yellow gold fan personally and I am getting married in Oct and my wedding band and hers are white gold. Now I have read and understand that if you plate rhodium over yellow gold rings that bc they are high wear items they frequently start having discoloration spots soon after. I was wanting to have these cufflinks plated with rhodium and since they are not high wear items not to concerned about discoloration. But I was wondering if the electroplating process might effect the mother of pearl of which they are set? Has anyone run across this problem?

A. It is wise of you to wonder about this because mother of pearl will be attacked by the chemistry and become frosty. It's also possible these cufflinks are set with plastic in which case they should survive the processing just fine.Neil Bell

A. Most rhodium baths are acid- during plating process mother of pearl must be protected with good protective clearcoat(after plating clearcoat must be removed!).Hope it helps and good luck!Goran Budija
A. Of course any responsible jeweler would remove the pearl and setting before having the item plated.
Every time I've sent a pendant, ring, or something with a stone out to be plated I've removed the stone and sent JUST what I wanted plated.
