A cluster of large, well formed Tetrahedrite crystals with sharp edges and tetrahedral habit. Many of the crystals have beveled terminations. There is a thin coating of micro Pyrite crystals on some of the crystals which have a slight green cast in color. There are several radiating sprays of short Quartz crystals in several places. The Quartz is white to clear in color. On the bottom of the specimen, there is massive, black colored Sphalerite and more micro Pyrite crystals.
