One excellent thumbnail specimen of space developed thin quartz crystals, forming a net of crystals covered in some points with small pyrite, chalcopyrite and sphalerite crystals
An excellent tumbnail specimen of galena crystal showing skeletal development with some signs of later dissolution.
An excellent cabinet size specimen of rhodochrosite spherolites, developed on the top of thin clear quartz crystals. In the end were developed Large sphalerite-marmatite crystal and small chalcopyrite crystals.
A very nice cabinet size specimen of galena, particularly covered by chalcopyrite. Galena is presented by cubic crystals with rounded edges, due to dissolution, and lately oxidated and coated in some parts by covelite. Chalcopyrite also shows change of color, to darker color, because of oxidation. Chalcopyrite is internally dissolved and replaced in some parts by shiny small pyrite crystals.
A nice specimen of very well terminated and lustrous cubic galena crystals in some places covered by small chalcopyrite crystals. The crystals are rounded by secondary dissolution.
One just unique, cabinet size specimen of well shaped cascade galena crystals, slightly dissolved, with small chalcopyrite crystals. One of the galena crystals, clearly show number 3.
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
