White stepped scalenohedral calcite crystals with a brownish interior with botryoidal chalcopyrite (blister copper) from the Tonglüshan Mine in Daye Co., Hubei, China. Another generation of chalcopyrite has partially grown on it. In two areas dark blue tarnished botryoidal chalcopyrite is overgrown by calcite, making it glow blue through it.
