Great apple-green color on this cuprian smithsonite from the 79 mine, Arizona. Almost electric. Great smithsonite formation and luster. An uncommon variety. $35

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!
