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.
One exceptional, large cabinet size specimen, with green sphalerite and very high transparency, developed on the top of galena crystals and chalcopyrite. Specimen has a cut base.
A very nice cabinet size specimen of step developed cubic galena crystals with signs of dissolvation in the last stages of mineralisation process. There also a part of broken chalcopyrite crystal on the top of galena
A large cabinet size specimen presenting isolated well terminated galena crystals overgrought by chalcopyrite.
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
An excellent double terminated group of two quartz crystals, overgrought by well developed chalcopyrite followed by sphalerite and second generation quartz.
An extraordinary cabinet size specimen of space developed quartz with galena, sphalerite, and chalcopyrite, secondary oxidized to bornite and covellite
An excellent, large cabinet size specimen, presenting galena crystalized on chalcopyrite, and after particular desolvation, corroded by pyrite replacing chalcopyrite and galena
A miniature size specimen of excellently developed chalcopyrite crystals particularly covered by sphalerite – marmatite and quartz.
