Description
Several well formed, strip-shaped, metallic crystals of rare thallium-lead-arsenic-sulfosalt Hutchinsonite from the well known Peruvian locale Quiruvilca of Santiago de Chuco province. The Hutchinsonite here is sharp edged and wonderfully striated and accompanied by raven-black Sphalerite and brassy Pyrite. Definitely a good and relatively rich specimen of a rare species.
