Mercedes Calcite (Chalcopyrite on Calcite) - Specimen fossil preparation specimen Pyrite often breaks during theMined from: Daye Mine, Huangshi, Hubei Province, China Description: This specimen is a tight cluster of tabular calcite crystals, arranged in overlapping, angular growth that gives the piece a compact but highly dimensional look. The crystals are clear to slightly milky, with broad, flat faces that catch light in a soft, glassy way. Running through many of these faces are bold, dark linear bands that cut cleanly across the crystal planes, creating a
