Manganocalcite with pyrite

A very nice and aesthetic specimen of well terminated, light pink color manganocalcite crystals with rhombohedron after scalenohedron crystals, covered by small and very shiny pyrite crystals.

Galena,sphalerite,pyrite and quartz

A Large and extraordinary beautiful specimen of mirror shiny well-shaped galena crystals, lustrous sphalerite(marmatite) and pyrite.

Sphalerite, pyrite, galena and calcite

An aesthetic specimen presenting pyrite and galena developed on mother rock, followed by very well shaped sphalerite(marmatite0 shiny crystals, covered by rhombohedral crystals of calcite

Chalcopyrite, sphalerite, galena, pyrite and quartz

A very aesthetic and attractive specimen showing almost full paragenesis set – Chalcopyrite, galena, sphalerite, pyrite, and quartz. The specimen is strongly oxidated – galena crystals lose their luster and chalcopyrite is oxidated with different stage and coated in some places by bornite.

Chalcopyrite, galena, pyrite and sphalerite

An excellent specimen built large, very well terminated and shiny chalcopyrite crystals corroded by galena, pyrite and sphalerite. On some of the chalcopyrite crystals could be seen „elephant skin“ what is usually sign for internal dissolution and recrystallization – in that case, replaced by galena and pyrite.

Calcopyrite, galenaq sphalerite and quartz

A nice specimen formed by several large chalcopyrites well-shaped crystals developed on quartz and overgrought by sphalerite and galena. Oxidation gives to chalcopyrite deep dark gold color

Manganocalcite , quartz and pyrite

Exceptional and very aesthetic specimen presenting flat manganocalcite crystals developed on thin transparent quartz crystals, followed by shiny well shaped cubic pyrite crystals. Some of the pyrites have rainbow effect, due to a thin coating of bornite-covellite as result of the oxidation process.
