Calcite Quartz and Chalcopyrite
Availability: 1 in stock
Always on the search for unusual calcites, I happened upon this large plate from Azerbaijan. The crystals have a pearly look near the terminations and are scalenohedrons modified by the prism and the rhombohedron. They reach over 5cm and are doubly terminated and undamaged.
Locality: Dashkesan Mine, Azerbaijan
