I’ve been asked to repair a sterling barrette that has a coral cabochon. The barrette clasp is attached to the plate via two small posts at the back. This will be my first repair job.
I’m trying to decide whether to remove the stone or go ahead with it in place. I’d rather not remove it. I’ve read that coral is exceptionally sensitive to heat, but these prongs are a good distance from the bezel. Is surrounding the cabochon in wet paper towel sufficient? I’m working with a Smith little torch on oxy-acetylene.
Thanks for any help!
