Rare green quartz – prazem, galena, pyrite, chalcopyrite and quartz

One beautiful and rare cabinet size specimen, presenting almost full paragenesis set of Madan deposit. Galena is with large cubic skeletal crystals and mosaic developed crystal faces, overgrowth by large green quartz crystals and chalcopyrite, which is secondary oxidated and replaced by pyrite well shaped shiny crystals.

Chalcopyrite, pyrite and galena

One very interesting specimen of chalcopyrite and pyrite on mother rock, followed by galena. Chalcopyrite is internally corroded and replaced by small pyrite crystals. Galena crystals are particularly corroded and coated by bornite.

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.
