I had a customer come in that had lost a matching wedding band in the mail.  After we matched the lost ring and made it new,  she brought in an earring that she had lost the mate to.  She inquired about making a match for that as well.  So we were going to make a mold of the earring,  and decided that we would just cad cam instead so that it would match and not loose size in the  refinishing process.  Below is the new found complete pair of matched earrings!
