I have a size reduction repair to a sterling shanked ring with a
large CZ stone.
-
Can the CZ safely be placed in Boric Acid?
-
To remove the firescale protection, can the CZ go into pickle or
how can it be removed? -
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.
