Tetrahedrite and Galena on Quartz

Although the Sweet Home mine is most famous for its Rhodochrosite specimens, the most significant sulfide in the mine is Tetrahedrite. This specimen hosts several good quality Tetrahedrite crystals measuring up to 6 mm with great luster, sharpness and a slight amount of associated minerals include Galena and Pyrite which are sitting on a beautiful “plate” of gem quality “needle” Quartz, which was indicative of the pieces that came during this period. The piece was collected by my father, Richard Kosnar, and my grandfather, Dave Bergman, in late 1977.
