A very aesthetic cabinet size specimen presented by cluster of elongated completely transparent quartz crystals on mother rock with small pyrite crystals in the base of the quartz
A very nice and aesthetic specimen of Longaxes needle quartz overgrought sphalerite, galena, and sphalerite. There are light oxidation signs on pyrite as result of coating by bornite.
One of the last cabinet size specimens from our closed mine Eniovche, famous for its curved rhodochrosite crystals. Rhodochrosite forms well terminated curved crystals covered with small clear quartz-rock crystals and with some pyrite crystals
An excellent, large cabinet size specimen, presenting galena crystalized on chalcopyrite, and after particular desolvation, corroded by pyrite replacing chalcopyrite and galena
A nice specimen of very lustrous long-needles quartz, space developed on the base of galena, sphalerite, and pyrite. Lately on quartz needles were developed calcite aggregates.
An attractive specimen of well-terminated pyrite with very lustrous crystal faces, singenetically developed with transparent quartz – rock crystal and followed by sphalerite and galena.
A specimen of shiny small galena and sphalerite crystals, followed by bigger pyrite crystals, particularly oxidated and coated by bornite. All these minerals are covered by extremely shiny, long-axes, needle quartz crystals, very well space developed and forming a set of crystals
A very attractive specimen, presenting very well space developed long-axes transparent needle quartz, covering sphalerite, galena, and pyrite crystals
A unique for Bulgaria specimen presenting space developed transparent quartz – rock crystal with very well terminated shiny pyrite crystals coated by iridiscenting bornite and covellite as result of oxidation of , most likely coating of chalcopyrite
A large cabinet size specimen, presenting almost full paragenesis of Madan with very complicated mineralization process. Pseudomorph of pyrite after chalcopyrite, on the top of small galena crystals, followed by quartz and small sphalerite (cleophane) crystals
