One very nice cabinet size specimen, presenting group of large galena crystals with signs of dissolution on the top of chalcopyrite corroded and replaced by pyrite, followed by quartz.
A very nice small specimen of well developed quartz crystals overgrowth by chalcopyrite and sphalerite.
One beautiful specimen of very aesthetic, perfectly shaped thin quartz crystals with very lustrous crystal faces with well developed pyrite crystals,slightly oxidized to red color.
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.
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.
One stunning cabinet size specimen of several chalcopyrite crystals,coated by bornite and covelite and covered by transparent, radial developed quartz crystals.
A beautiful cabinet size specimen presenting very well terminated galena crystals with sphalerite and pyrite, covered by thin long-axes transparent quartz crystals
A magnificent cabinet size specimen of quartz-rock crystal, building space developed net of crystals. Due to start of crystallization from one center, most of the crystals form flower like groups
One extraordinary specimen of single manganocalcite pink crystal, singenetically developed with small transparent rock crystal,green prazem quartz crystals, pyrite and sphalerite.
An excellent thumbnail of transparent clear quartz covered by calcite aggregate of small calcite crystals and in the end of crystallization process with one rhombohedron crystal developed on pyramidal face of the larger quartz crystal.
