Тип минерал: sphalerite
Sphalerite – marmatite, galena chalcopyrite and prazem – green quartz
One excellent specimen presenting singenetically developed skeletal galena crystals and one very well developed sphalerite – marmatite with „snake skin“ surface, on the top of light green quartz – prazem.
Chalcopyrite, galena, sphalerite, pyrite and quartz
A beautiful and very aesthetic cabinet size specimen of chalcopyrite crystals on the top of galena and sphalerite, followed by quartz. Chalcopyrite crystals are internally corroded by pyrite.
Galena, chalcopyrite, sphalerite and quartz
One very rare, cabinet size specimen, showing strongly dissolved galena, followed by quartz sphalerite and chalcopyrite. Chalcopyrite crystals are also subject of dissolution and have rounded edges.
Quartz, sphalerite, pyrite and chalcopyrite.

Galena with pyrite, quartz and sphalerite
One small beautiful specimen of sphalerite and galena mother rock overgrowth by quartz pyrite and galena
Transparent green sphalerite – cleophane with quartz
An excellent small specimen of transparent to translucent sphalerite – cleophane crystals on quartz base. Sphalerite is with lustrous crystal faces and isometric rounded shape.
Galena with sphalerite – marmatite
One very attractive cabinet size specimen presenting large cubic galena crystals on the top of black lustrous marmatite crystals.
fragment of sphalerite- cleophane crystal convenient for cutting-faceting
An excellent completely transparent fragment of sphalerite-cleophane crystal with yellow-green to light green color. Specimen is convenient for faceting. Pictures are taken in transmited (back) light in cold LED light, what make green color stronger.
