A four in one small cabinet combination! A single, lustrous, terminated crystal of Calcite caps a two sided matrix that could be a different specimen from each side. Dolomite crystals with minor Chalcopyrite covers one side, while the reverse is largely covered in octahedral crystals of Galena over the Dolomite and Chalcopyrite. An endlessly explorable piece.
