A gorgeous specimen of clear quartz-rock crystal and sphalerite, overgrowth by rhodochrosite, followed by chalcopyrite and stilbite
An amazing small specimen of rhodochrosite overgrowth by black, very well terminated sphalerite- marmatite, chalcopyrite corroded by pyrite, galena, and quartz
One very aesthetic and rare specimen of clear and lustrous quartz crystals, overgrowth by black and opaque sphalerite-marmatite, followed by chalcopyrite and pyrite.
An amazing, and extremely aesthetic specimen of quartz, followed by galena and sphalerite, overgrowth by chalcopyrite, corroded by pyrite.
One very rich of minerals specimen build in quartz, followed by sphalerite – marmatite, galena and overgrowth by chalcopyrite and pyrite.
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.
An amazing specimen of pyrite, chalcopyrite, sphalerite, and quartz, followed by rhodochrosite. At the end of the crystallization process were developed small. double ended stilbite crystals.
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.
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.
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.
