Rainbow pyrite, quartz

An excellent double face, cabinet size specimen, formed of well-shaped pyrite crystals on one side, coated on some crystals by bornite and covellite. On the other side of the specimen, pyrite is particularly overgrowth by think quartz crystals.

Calcite, quartz-rock crystal, green quartz, pyrite and galena

A rare and very beautiful specimen of galena and pyrite followed by clear long quartz crystals, covered by green quartz colored by chlorite and overgrowth by thin grain calcite. On the top of the specimen is developed large translucent calcite crystal with clearly  twined down part of the crystal

Chalcopyrite, quartz , Pyrite

A beautiful large cabinet size specimen, of short quartz crystals, overgrowth by well terminated large chalcopyrite crystals, internally dissolved and replaced by pyrite. Chalcopyrite is coated by bornite and covellite, due to the oxidizing process.

Green quartz – prase, galena, sphalerite, marmatite,

A very aesthetic cabinet size specimen of cubic galena overgrowth by green quartz – prase ( colored by chlorite) and followed by a very lustrous group of black sphalerite – marmatite crystals with several clear twins. In the later stages of crystallization, galena was strongly dissolved,  and  quartz are standing in a  very attractive space net of crystals.
