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.
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
One beautiful specimen of galena overgrowth by small chalcopyrite crystals and green translucent sphalerite – cleophane.
One very interesting specimen of chalcopyrite and pyrite on mother rock, followed by galena. Chalcopyrite is internally corroded and replaced by small pyrite crystals. Galena crystals are particularly corroded and coated by bornite.
An very aesthetic specimen of group of quartz crystals with sphalerite, galena and chalcopyrite
A beautiful cabinet size specimen presenting very well terminated galena crystals with sphalerite and pyrite, covered by thin long-axes transparent quartz crystals
One cabinet size extraordinary cluster of galena crystals with perfect crystal faces, which could be used as a mirror. The crystals have particularly skeletal development.
One excellent floater of galena with block developed part of the cluster and another part with skeletal development, on the top of black sphalerite-marmatite.
