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.
A very nice, small specimen of clear quartz crystals with very lustrous crystal faces, overgrowth by black sphalerite.
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.
One very aesthetic, large cabinet size specimen of quartz build in long-axes extremely clear and lustrous quartz crystals, growing in an attractive cluster.
An outstanding specimen of reconstructed galena, developing spinel law twinned crystals, overgrowth on the backside by excellent transparent quartz crystals.
