An exceptional, aesthetic, cabinet size specimen of pyrite coated by bornite and covellite and showing incredible color play.
Тип минерал: bornite
Chalcopyrite, Galena, sphalwrite-marmatite, quartz and rhodochrosite
One unique specimen of galena, overgrowth by large bright chalcopyrite crystals with very aesthetic striation on the crystal faces and followed by quartz and black sphalerite – marmatite. In the end of the crystallization process crystalized several beautiful hallow rhodochrosite crystals, following the shape of dissolved calcite crystals.

Chalcopyrite, pyrite, bornite, covelite
An outstanding and extremely rare specimen of pseudomorph of pyrite after sphalerite and chalcopyrite, on quartz.. Giudurska mine, Erma reka, Zlatograd area, Bulgaria
Galena chalcopyrite, bornite, covellite, pyrite
One very aesthetic – autumn style specimen of chalcopyrite, developed on the base of quartz crystals. Chalcopyrite is secondarily corroded (dissolved and replaced) by pyrite, and the internal pressure of crystalizing crystals crack the mother crystals and cemented these cracks. Chalcopyrite is coated by bornite and covellite during the oxidizing of their surface.
Chalcopyrite, bornite, covelite, sphalerite, galena
One amazing small specimen of chalcopyrite, sphalerite, galena, quartz and pyrite. Chalcopyrite crystals are corroded and oxidated to bornite and covelite on their surfaces.
Galena, chalcopyrite,sphalerite – marmatite and quartz
An excellent specimen of galena cubic crystals, overwrought by chalcopyrite and followed by sphalerite and quartz
Rainbow pyrite with quartz
One very nice , cabinet size specimen of well terminated cubic pyrite crystals, covered by quartz strongly oxidated to bornite in some parts of the specimen.
Chalcopyrite, quartz, galena, sphalerite, bornite and covelite
An aesthetic cabinet sized specimen of large chalcopyrite crystals, singenetically developed with galena and sphalerite, followed by quartz. In the last stage of crystallization, oxidation creates a thin coating of bornite and covellite.
Quartz and chalcopyrite
Well shaped chalcopyrite crystals fallowed by white quartz crystals. Chalcopyrite is particlularly oxidated and coated by bornite and covelite. On some of the crystals some parts are coated by bonite and other by covelite, what most likely is due to dirrection of solutions flowing
