Anyone have a list?
What is the reaction/damage from?
Obviously emeralds can lose treatment and pearls can be eaten by the acid, but I know that tanzanite and peridot can come out looking ‘frosted’ and need repolishing after a short period in the solution, while jadeite and kunzite seem to be fine… so I don’t think it’s an issue of hardness (but of course, could be wrong)
Thanks in advance!
