A very attractive, aesthetic specimen of galena and pyrite lustrous crystals, overgrowth by extremely lustrous, well-shaped black sphalerite crystals with tetrahedral habit. In marmatite, there are several twinned 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.
A beautiful specimen of Chalcopyrite, bornite, covellite, sphalerite-marmatite, galena
Size: 50 x 36 x 13 mm
The specimen that you receive may look slightly different in color from the one in the photographs, because of the lights used to make the photos.

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.
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
