Sold! Double terminated calcite from the Portland Mine, Arizona. Uncommon to see a DT calcite crystal, this has great form and clarity, and absolutely no cleaving present. Only $40.

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!
