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.

Galena, manganocalcite and quartz

One very aesthetic and and rare specimen of small quartz crystals overgrowth by cubic galena crystals, lately strongly dissolved and followed by single, very well shaped steep scalenohedral crystal of manganocalcite

Calcite and manganocalcite

One very rare specimen, combination of two steep scalenohedron manganocalcite, overgrowth by transparent calcite – forming phantom inside transparent calcite

Epidote with manganocalcite

One unususal and rarest mineral combination in deposit Laki. Small, green, spherolite orientated needles of epidote in combination with large pink manganocalcite crystals
