A nice group of pyrite crystals with very well developed crystal faces with striation.
One excellent, large cabinet size specimen presenting a very aesthetic cluster of quartz crystals -druzy, developed in lustrous, transparent long-axes crystals in some places with small shiny pyrite crystals.
One attractive specimen presenting almost full paragenesys set of deposit Madan. Very well shaped and shiny sphalerite crystals singenetically developed with lustrous galena crystals, showing „waves“ of dissolution, and corroding together with sphalerite, pyrite and quartz dissolved chalcopyrite.
An excellent, large cabinet size specimen presenting almost full sulfide paragenesys of deposit Madan. Large crystals of chalcopyrite was dissolved and particularly replaced by pyrite, galena and black sphalerite- marmatite.
An large cabinet size classical galena specimen with large cubic galena crystals. Galena is with well developed crystal faces and with some skeletal development signs.In the end of the mineralization process there was strong dissolution, resulted as „fingerprint „signs on the crystal faces. The back side of the specimen is covered by green quartz – prazem overgrought by pyrite.
An extraordinary specimen showing typical for Madan secondary dissolvation and replacement of chalcopyrite by pyrite. The large chalcopyrite crystals are internaly dissolved and replaced by sphalerite and pyrite. In the end of mineralisation process, take part oxidation and coating of chalcopyrite by bornite and covelite
A beautiful and very aesthetic specimen in cabinet size presenting almost full paragenesis set of Madan. Specimen is build in sphalerite, galena and pyrite overgrought by very thin, long axes quartz needles forming space developed net with quartz stars. In the late stage of crystallization were formed small pyrite crystals, used as a seed for developing of transparent quartz crystals,after deposit on galena, pyrite and sphalerite crystals continue their development forming an excellent space net.
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
