Calcite with iridescent Chalcopyrite

Item Description

A showy and classic specimen of the famous Brushy Creek Calcites featuring eye-catching smoky colored, well-formed, "dogtooth"-shaped crystals with sharp, well-formed faces which are partially coated by beautiful rainbow iridescent Chalcopyrite. The largest Calcite crystal measures 7.2 cm long. No real damage that I can see (with the exception of the back where the piece was removed from the pocket wall), and the specimen is highly displayable and three-dimensional. Classic material, that was at one point fairly plentiful on the market, but is now rather hard to find.
