b89 CALCITE, DOLOMITE, CHALCOPYRITE, Kansas, 10 x 7 x 3.5 cm | |
Two large nail head Calcite crystals on a matrix of Calcite and Chalcopyrite. The backside is a matrix of Dolomite and Chalcopyrite. The main Calcite has an area of contact or damage at the one termination. The second Calcite has a cleave on the backside of the termination. Still a nice example of a tri state Calcite. |
