Calcite : CaCO3

Roosevelt Avenue Quarry (York Stone Quarry), York, York Co., Pennsylvania, USA

12.9 x 7.4 x 4.9 cm. A large and superb York County calcite, out of the Feist Collection. Surface inclusions of iron impurities giving the calcites from this mine this dazzling orange color. This is a single very large crystal with micro-stepping all over its faces. It is complete all around and uncontacted, and absolutely glows under good light.
