A choice cabinet-sized Calcite specimen from a locality 250 feet BELOW the Chicago suburbs! It features numerous lustrous crystals of clear Calcite arranged into the gracefully composed formation pictured. Many of the Calcite crystals contain inclusions of very SPARKLY golden Marcasite. In some of the Calcites it can be seen that the Marcasite crystals are outlining internal PHANTOMS which would otherwise be barely visible. Loads of amazing details for you to explore over all sides of this remarkable piece.
