I knew this guy who traded in opals (a semi-precious stone)and sapphires, and this is what he told me:
The gem you have is valuable if it has a continuity of color and texture, and no suspended dirt-like particles inside it. It should NEVER have internal fractures (this reduces its value greatly: avoid falls that could cause this). And it should have little water content (the place it was extracted from should be relatively dry. There are methods of drying out hydrates in gems, but I don’t know about that).
The working process is done by a skilled gem cutter using a lapidary spinning wheel usually coated with silicon carbide or diamond particles.
Hope this helps.

Ive been a gem cutter for nearly 35 years…Gunner is right on his points about opal, but your case is a little different with what you have…If you would like to email me at or IM me at tahoeman_69, I would be happy to discuss everything you would like to know…It is really more involved than I can describe here and I think it would help to uncomplicate the process if we talked via messenger…
