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, shalerite, chalcopyrite, pyrite

An absolutely outstanding cabinet size specimen of large and very well terminated galena crystals, a combination of cubes and octahedrons, followed by sphalerite chalcopyrite and pyrite.

Chalcopyrite, galena, sphalerite, calcite, quartz

One very rare cabinet size specimen, presenting chalcopyrite, galena, sphalerite, quartz, and calcite. The chalcopyrite crystals are very unusually elongated in the direction of „C“ ax, instead of the usual tetrahedral crystals.

Galena chalcopyrite, bornite, covellite, pyrite

One very aesthetic – autumn style specimen of chalcopyrite, developed on the base of quartz crystals. Chalcopyrite is secondarily corroded (dissolved and replaced)  by pyrite, and the internal pressure of crystalizing crystals crack the mother crystals and cemented these cracks. Chalcopyrite is coated by bornite and covellite during the oxidizing of their surface.
