Sold! Azurite Geode from the Blue Ball Mine, Arizona. This has been cut open revealing a very striking crystal core. Kind of reminds me of a thunder egg with the lightning bolt pattern. Great color and great specimen all around. $100.

This is a very nice opal on matrix from a rare locality! From Spencer Idaho; this area produces some really amazing opal! I got this piece a little wet to show off the colors and the flash a little better. But amazing coverage of color all over the piece! $90!
