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.
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.
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 cabinet size specimen of sphalerite – marmatite and chalcopyrite, covered by spherulites of rhodochrosite, lately strongly dissolved
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.
A beautiful specimen of Chalcopyrite, Sphalerite-Marmatite
Size: 48 x 44 x 38 mm
A specimen that you receive may look slightly different in color from the one on the photographs. Because of the lights used to make the photos.
