A very nice and aesthetic pseudomorph specimen of elongated crystals of stilbite and small spherolites of dolomite, covered and replaced by tiny quartz crystals.
Beautiful specimen of extremely well terminated black opaque sphalerite – marmatite, on the top of transparent clear quartz crystals. Marmatite form a tetrahedral crystal with well terminated lustrous faces.
One excellent, cabinet size specimen of quartz followed by galena and overgrowth by sphalerite-cleophane. Sphalerite crystals are isometric, with rounded corners and with very high transparency in some parts. Color is green to yellow-green.
A very rare large cabinet size specimen, presenting spherolites of small curved rhodochrosite crystals on the top of transparent quartz crystals. Due to different presence of manganese in that spherolites, their color vary from yellow to orange color.
A very aesthetic, large cabinet size specimen of aragonite aggregates on quartz
One stunning cabinet size specimen of several chalcopyrite crystals,coated by bornite and covelite and covered by transparent, radial developed quartz crystals.
An very aesthetic, large cabinet size specimen of isolated clusters of green quartz-prazem on the top of calcite and manganocalcite, with galena and sphalerite.
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.
An amazing, large cabinet size specimen of mirror shiny galena with very lustrous black marmatite and transparent quartz crystals, covered by white calcite
An very aesthetic specimen of group of quartz crystals with sphalerite, galena and chalcopyrite
