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.

Sphalerite,galena rhodochrosite and prazem quartz

An aesthetic cabinet size specimen developed on a base of galena and black sphalerite-marmatite fallowed by rhodochrosite, which was secondary dissolved. At the end of the crystallization process were developed transparent quartz crystals and green quartz – prazem.
