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.
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.
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.
An very aesthetic specimen of group of quartz crystals with sphalerite, galena and chalcopyrite
An exceptional transparent cabinet size specimen of small isometric grain of sphalerite with yellow – green color, and complete transparency.
A beautiful cabinet size specimen presenting very well terminated galena crystals with sphalerite and pyrite, covered by thin long-axes transparent quartz crystals
One very aesthetic small – tumbnail size specimen of several transparent cleophane crystals with green – yellow-green color.
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.
