Calcite with Chalcopyrite (ex Brian Kosnar collection)

Item Description

The Braen's Quarry in New Jersey has been a seldom collection quarry for year, but has been a source of excellent Zeolite specimens and associated species. This piece features no Zeolites, but it hosts lovely golden Calcite crystals up to 1.9 cm which are associated with small sparkling crystals of golden Chalcopyrite on Quartz on matrix. There are also a few thin, bladed "casts" or epimorphs after Anhydrite on the edges of the piece as ewll. You can see the Chalcos under magnification, and I photographed them under the microscope to better illustrate their quality. A wonderful example from this well known NJ locale.
