A few clusters of heavily-intergrown Tetrahedrite crystals are attached to the quartz base of this cabinet specimen. Though these crystals have been damaged and are incomplete, the damage occurred during their formation and is partly healed over- most are in very good condition. The largest of these appears to measure about 0.5" (1.3 cm) in diameter. Those that are complete and not heavily intergrown show excellent tetrahedral form, and all show the standard black-gray color and semi-metallic luster. They are accompanied by a layer of crystalline sphalerite that is sandwiched between them and the quartz base, veins of pyrite that run through the base, and scores of beautifully-formed quartz crystals that coat the rest of the base.
