More information
These stones and their close cousin, white or milk opal are some of the best known opals in the world because of the fact that crystal and white opal have been mined for centuries, if not for thousands of years. European supplies came from the opal mines in Hungary which are all but mined out now.

The difference between crystal and white opal is that crystal is more translucent, in that you can actually see down deep into the stone. White opal is opaque, the color being on the surface of the stone. Crystal opals are the more expensive variety.

Where do they come from?

Crystal opal shells mainly come from the Coober Pedy fields in South Australia

Description This opal is actually a fossilized shell that has been carved to the original shape of the fossil

    Please tell me a bit more about this opal. Is it an actual shell or a lump of opal carved like a shell? How is it possible for a shell to be opal?
