TC69AF6: Aggregate of twinned Chalcopyrite crystals with the dominant forms of a disphenoid. They are very well defined and bright and have cubic Pyrite crystals on the back; small Galena crystals are associated. The chalcopyrite crystals are partially coated by groups of lenticular Calcite crystals. A classic piece from Cavnic, where good Chalcopyrite specimens are very scarce.
