Calcite and Marcasite from the Linwood mine, Iowa. Beautiful calcite Scalenohedrons with inclusions, on matrix, accompanied by nice Marcasite. $60.

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!
