An excellent cabinet size specimen of galena, overgrowth by chalcopyrite tetrahedral crystals. The chalcopyrite is internally dissolved and replaced particularly by pyrite – small pyrite crystals cut the surface of the mother chalcopyrite crystals. The second generation of a galena-bearing solution formed a large galena crystal, which covered most of the chalcopyrite crystals, but some of the ends of these crystals stay out. At the end of the crystalization process, the white quartz overgrowth all of the early formed crystals.
One exceptional and very rare floater of quartz overgrowt by chamosite, and coated by limonite
A gorgeous and very aesthetic cabinet size specimen of chalcopyrite, sphalerite, and galena, covered by rhodochrosite and small clear quartz crystals, followed by double-terminated translucent stilbite crystals. The specimen has a cut base.
A delicate an d very aesthetic specimen of long axes clear amethyst crystals with the phantom spreading of color.
An amazing, cabinet size specimen presenting a large, white, strongly dissolved quartz crystals overgrowth by small plate, brown-green zonal barite crystals.
One excellent, large cabinet size specimen, of quartz, overgrowth by large, very well-developed galena crystals segmented formation, followed by chalcopyrite and black sphalerite-marmatite. Galena is strongly dissolved in the last stages of crystallization, forming fingerprint signs.
One stunning large cabinet size specimen of black, lustrous sphalerite-marmatite large crystals developed on clear quartz, overgrowth by very well crystallized galena crystals – a combination of cub and octahedron, with mirror lustrous crystal faces. Galena is overgrowth by large chalcopyrite crystals, lately dissolved and replaced internally by small pyrite crystals.
An outstanding cabinet size specimen of pyrite, galena, and sphalerite overgrowth by small clear quartz crystals covered by rhodochrosite. At the end of the crystallization process, on top of all minerals were developed small double-terminated stilbite crystals.
Two excellent samples of sphalerite’s varieties – transparent green sphalerite – cleophane and black and very lustrous crystals of marmatite
