Manganocalcite, rhodochrosite, galena, sphalerite, chalcopyrite, quartz

One very rare specimen of manganocalcite crystals, developed on the base of black sphalerite – marmatite and followed by chalcopyrite crystals. At the end of the crystallization process on the surface of the specimen start crystalization of very light, pink rhodochrosite, curved crystals overgrowth by clear small quartz crystals.
