Association of black highly lustrous sphalerite crystals showing very sharp edges and well defined mirror-like faces, which is not typical of the species, partially covered with smaller colorless crystals of dolomite and calcite that produce a deep and nice contrast. The specimen has been kept by a local miner in pristine condition, free of any damage, since its extraction some time between years 1994-2002. Contains several spinel-law twins on the octahedral {111} face as can easily be appreciated in the photos. Overall size: 124 mm x 87 mm x 39 mm. Major crystal size: 29 mm on edge. Weight: 471 g. Unfortunately this is a not photography friendly specimen.
