Calcite with Chalcopytite and Marcasite (classic find, 1980s)

Item Description

A showy and complete Calcite cluster from the well-known Brushy Creek Mine from the famous and still unique pocket of the late 1980s. The lustrous, white to grey Calcite scalenohedrons range up to 3.5 cm. Far more translucent that you normally find from here, the Calcites are instantly recognizable with their preferential coating of sparkly Chalcopyrite and/or Marcasite crystals. The sulfides have good luster, and a light iridescence whose colors cover much of the spectrum. Distinctive and choice, this is classic material for the Brushy Creek mine. It was worked briefly in the mid-1900s and also in a more recent specimen-mining venture by Joe Kielbaso and friends in the late 1980s, from which this came. A stunning, balanced, perfect miniature from this classic find. It remains unique today. Valued $750-1000. From our special collection sale, direct to auction, of choice material from the collection of Richard Rossi, East Coast collector and Mineralogical Record Fellow.
