A beautiful and very aesthetic specimen in cabinet size presenting almost full paragenesis set of Madan. Specimen is build in sphalerite, galena and pyrite overgrought by very thin, long axes quartz needles forming space developed net with quartz stars. In the late stage of crystallization were formed small pyrite crystals, used as a seed for developing of transparent quartz crystals,after deposit on galena, pyrite and sphalerite crystals continue their development forming an excellent space net.
An well terminated quartz crystals, developed from one center and cluster look like a flower. Cluster is well space developed, and form circle structures.
An excellent double terminated group of two quartz crystals, overgrought by well developed chalcopyrite followed by sphalerite and second generation quartz.
A very aesthetic cabinet size specimen presented by cluster of elongated completely transparent quartz crystals on mother rock with small pyrite crystals in the base of the quartz
An extraordinary cabinet size specimen of space developed quartz with galena, sphalerite, and chalcopyrite, secondary oxidized to bornite and covellite
An extraordinary cabinet size specimen of large quartz crystals covered with very well terminated bundles of stilbite crystals lately replaced by calcite and covered with quartz aggregates
An excellent miniature specimen showing a „cast“ of quartz, covering steep scalenohedron crystals, secondary completely dissolved.
A very aesthetic quartz – rock crystal developed on the top of rhodochrosite spherulite aggregates
An extraordinary specimen of clear- rock crystal quartz, with several well-presented Japanese law twins. In the late stages of the crystallization process, were developed several groups of gold color groups of needle celestine crystals
An attractive specimen of well-terminated pyrite with very lustrous crystal faces, singenetically developed with transparent quartz – rock crystal and followed by sphalerite and galena.
