This is a fascinating specimen with superbly defined prismatic, crystals, to 5 mm in length, of the rare lead, THALLIUM, arsenic sulfosalt Hutchinsisonite. They are nicely associated with multifaced, lustrous, brassy Pyrite crystals and black Sphalerite. The wonderfully striated Hutchinsonite here has steel gray colour, a fine and high metallic sheen and superb terminations. The specimen is nicely accented by burnt orange coloured rosettes of Orpiment. One of the finest pieces of the species we ever handled.
