A terrific off-matrix specimen of intergrown steely-grey Tetrahedrite crystals to 2.3 cm on edge from the remote 'nimas mine in the Atocha-Quechisla District of Bolivia. The upper face is composed of these larger Tetrahedrite crystals, with similar but smaller crystals making-up the base. Dusted across the Tetrahedrite on all faces are perfect octahedral crystals of metallic, brassy Pyrite, all to about 3 mm on edge; fine acicular druses of Boulangerite and thicker acicular crystals of Jamesonite.
