Great luster on this Calcite crystal perched on a cluster of smaller calcites from the famous Elmwood mine in Tennessee! I love the color and presentation of the piece. Available for $50

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!
