I have a size reduction repair to a sterling shanked ring with a
large CZ stone.
1. Can the CZ safely be placed in Boric Acid?
2. To remove the firescale protection, can the CZ go into pickle or
how can it be removed?
3. I understand I can heat protect the CZ in KoolJool or water and
just treat the shank but, I would like to understand the possible
effects, if any, on the CZ if "normal" processes are used including
Boric Acid and Pickle.
