Item Description

A CLASSIC known from the old books of the 1800s era of mineralogy, this is an old-time Cornwall specimen featuring matte-black Chalcocite crystals to 2.1 cm with an unusual twin habit, and a very rare association on calcite matrix. The bladed Chalcocites are sharp, and feature broad striations, of which these 'channels' are undoubtedly related to the twinning that is occurring on the 110 plane. The Chalcocites rest on thin wafers of crystallized Calcite, and both the Chalcocites and Calcites have a red Hematite tinge to them. This rich, venerable combination piece from the historic Levant Mine has a fine provenance, having been in the collections of Boubee (sometime before 1890) and then the British Museum (via an "E. White") before entering Kay's collection sometime in the 1980s.
