Several small Calcite prisms extend from the dolomitic limestone base of this large hand specimen. Though two of the crystals are broken and incomplete, the rest are undamaged and in good condition, showing excellent trigonal form. Their color is a rather dull, creamy-yellow, and their luster is a dull pearly. All are dimly transparent. They are accompanied by hundreds of tiny, white dolomites, scores of small chalcopyrites and several marcasite nodules that have likely pseudomorphed into pyrite.
