There are two methods that I am familiar with. One is heating the
setting until the pearl pops off. I am not a great fan of that method
because there is always the chance of damaging the pearl.
What we have found that works better is a product called "Attack"
which is designed to dissolve jeweler’s epoxy. You should be able to
find it at most jeweler supply stores. If you have trouble finding
some, let me know. We’ll help you out!
