Galena with chalcopyrite and pyrite

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.

Rhodochrosite with quartz,pyrite and sphalerite

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

Golden calcite with galena, pyrite and sphalerite

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

Galena,chalcopyrite, sphalerite and quartz

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.

Chalcopyrite with galena sphalerite-marmatite and pyrite

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.

Galena large crystals with green quartz- prazem and pyrite #799

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.
