This specimen is a slab chiseled from the wall of a hydrothermal vein. Numerous crystals of tetrahedrite to 0.5" (1.3cm) on edge are scattered over a matrix of galena, pyrite, quartz, manganocalcite, and bournonite. A few of the tetrahedrite crystals have minor damage to their tips, while others are undamaged. At least one of the quartz crystals is double terminated.
