One excellent specimen of rhodochrosite „cauliflower“ shaped spherolite crystals,covering highly transparent rock crystals developed in cavities.
One excellent, large cabinet size specimen presenting a very aesthetic cluster of quartz crystals -druzy, developed in lustrous, transparent long-axes crystals in some places with small shiny pyrite crystals.
An excellent cabinet size specimen of galena, with very lustrous and shiny faces. Crystals are developed in the cubic shape. Galena crystalize on the back side of tectonically broken quartz and reconstructed older galena generation.In the last stage of development there are signs of „desolvation waves“
A very rare specimen presenting two kind of sphalerite – marmatite ( black and opaque) and cleophane (transparent with yellow – green color). These two varieties alternate in the specimens and even in the crystals there are zones of marmatite and cleophane with very strong border according planes of cleavage. Morphology of the crystals is tipical for marmatite. Sphalerite covers galena and quartz.
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
