    Bournonite
    Pachapaqui mining dist., Bolognesi Prov., Ancash, Peru

    Bournonite is a highly sought-after sulfosalt originally found in Cornwall, but many fine pieces have come from Peru in the 1980s and 90s - this being one rare cabinet-sized specimen. A few dozen splendent, metallic-gray, columnar to blocky, flat-topped Bournonite crystals display prominently on this triangular-shaped piece of matrix. The shiny gunmetal-gray crystals vary between 1 and 2.5 cm in length and show prominent deep grooves parallel to their length largely a result of their complex twinning. This specimen is enormous for a Peru piece. The Bournonites are richly scattered amongst tiny (almost drusy), whitish, Quartz crystals, and even smaller (less than 1 mm) shiny Pyrite crystals. Many of the Bournonites that are set on their sides have the classic "cogwheel" crystal form. This is a very showy and important Bournonite specimen and superb for this particular locality. It holds its own with those from other, more contemporary production regions but is still distinctly historic and Peruvian. It was purchased in 2001 from Willis' Earth Treasures, East Coast Show, Springfield, Massachusetts.
