An extraordinary specimen of very well terminated cubic galena crystals, overgrowth bigger, mosaic galena crystal with singeneticaly developed sphalerite-marmatite.
An excellent small specimen of cleaved sphalerite cleophane. Plate is completely transparent and with zonal spreading of color in orange and green. The pate is very attractive as specimen, but also could be used for faceting. Picture is taken in common light- no back illumination.
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.
One very aesthetic specimen of galena with black, lustrous well shaped crystals of sphalerite-marmatite.
A nice piece of completely transparent fragment of sphalerite – cleophane crystal with trigonal pyramid shape. The color is with unequal spreading from yellow green to orange color. The specimen is convenient for faceting, Pictures are taken in transmitted light (back light).
One very well developed cabinet size specimen showing skeletal developed galena crystal on sphalerite and quartz.
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.
An excellent large cabinet size specimen with mosaic development of the crystals. This kind of aggregates are usually due to overgrought of large single crystal. One, some or all of the faces, start to grow with mosaic step mode and due ( most likely) to fast crystallization and unequal concentration of solutions, develop single crystal with individual temp of growing, but with joined direction of development and isolated crystals with inherited orientation.
