One stunning cabinet size specimen of several chalcopyrite crystals,coated by bornite and covelite and covered by transparent, radial developed quartz crystals.
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.
One beautiful specimen of galena overgrowth by small chalcopyrite crystals and green translucent sphalerite – cleophane.
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.
An very aesthetic specimen of group of quartz crystals with sphalerite, galena and chalcopyrite
One extraordinary specimen of galena on the top of black sphalerite- marmatite and chalcopyrite, followed by pyrite. Galena crystals are with rounded edges, due to strong dissolution
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.
