One small, but very nice specimen build in black and opaque sphalerite- marmatite around big transparent quartz crystal. Sphalerite is with skeletal development, overgrowth by large well-terminated cubic galena crystals.
An excellent cabinet size specimen, presenting flat calcite crystals ( paperspat) filling a cavity in the mother rock, fallowed by second generation of small yellow-brownish calcite crystals, covering quartz crystals.
One excellent specimen of rhodochrosite „cauliflower“ shaped spherolite crystals,covering highly transparent rock crystals developed in cavities.
One very aesthetic cabinet size specimen of quartz crystals overgrought by calcite and lately covered with several generation of calcite aggregates, In the end all minerals were coated by lemonite.
One very well developed cabinet size specimen showing skeletal developed galena crystal on sphalerite and quartz.
One nice cabinet size and very old specimen of curved small rhodchrosite crystals, covering quartz vertical crystals, singenetically developed with calcite.
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 tumbnail of transparent to translucent isometric sphalerite crystals on quartz aggregate
One attractive specimen presenting almost full paragenesys set of deposit Madan. Very well shaped and shiny sphalerite crystals singenetically developed with lustrous galena crystals, showing „waves“ of dissolution, and corroding together with sphalerite, pyrite and quartz dissolved chalcopyrite.
A large cabinet size specimen of very well space developed quartz crystals on the top of galena and sphalerite small crystals. Quartz is very well space developed, with white translucent crystals, starting their growth form one point in all directions, forming „stars“ of crystals.
