• Removing the dop wax as in your video…I am leery of thermal shock to the opal by undopping with the freezer…what are your thoughts?


    • Hello Audie There is no problem with the thermal shock with Australian opal. IF it comes from Ethiopia then I am not sure. The opal from Australia can take many temperatures. and in the last 25 years I have used the freezer method and never cracked an opal. even top gems. It really doesn;t matter. Regards Justin
