Sphalerite – marmatite, galena, quartz

One excellent specimen, presenting the classical shape of sphalerite crystals with a tetrahedral habit. Galena is developed on mother rock and later is strongly dissolved, forming “ dissolution fingerprints on the surface of the crystals. Galena is followed by transparent quartz – rock crystal, and at the end of the crystallization process were formed sphalerite tetrahedral crystals with several very nice and showed twins
