One extraordinary specimen of single manganocalcite pink crystal, singenetically developed with small transparent rock crystal,green prazem quartz crystals, pyrite and sphalerite.
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
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 large cabinet size and very attractive rhodochrosite specimen with very intensive pink color. Rhodochrosite is presented in two generations – one forming typical spherolites hemispheres, which is followed by sphalerite and pyrite and second which is with smaller crystals with intensive color, covering bigger part of earlier minerals. In the end crystallized small transparent quartz crystals
An excellent cabinet size specimen of well shaped small crystals of galena, sphalerite and pyrite overgrowth by very lustrous rhombohedrons of golden color calcite with mosaic surface.
size 84 x 40 x 45 mm
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.
