Extremely well-developed galena crystals with mirror shiny faces and interesting skeletal developed combinations of the octahedron and cubic crystal form.
A beautiful specimen presenting well-terminated galena cubic crystals, covered by chalcopyrite and sphalerite-marmatite with green quartz on the top.
A large cabinet size specimen, presenting almost full paragenesis of Madan with very complicated mineralization process. Pseudomorph of pyrite after chalcopyrite, on the top of small galena crystals, followed by quartz and small sphalerite (cleophane) crystals
An aesthetic cabinet sized specimen of large chalcopyrite crystals, singenetically developed with galena and sphalerite, followed by quartz. In the last stage of crystallization, oxidation creates a thin coating of bornite and covellite.
A very aesthetic cabinet size specimen of long-axes needle quartz crystals, with very lustrous crystal faces, overgrowing base of combined sphalerite and galena small crystals and a little bigger pyrite crystals, showing in some places traces of oxidation and coating by bornite.
An excellent example of well space developed mosaic skeletal galena crystal followed by several transparent to translucent cleophane crystals and green quartz crystals
Very aesthetic specimen presenting well-terminated cubic galena crystals singenetically developed with chalcopyrite.
A very aesthetic specimen of galena covered with small pyrite and overgrought by transparent , long axes, and very shiny quartz crystals
Very aesthetic specimen build in large and very well terminated galena crystals. Crystal faces are with equal developed octahedron and cubic crystal form, on the base there are small calcite crystals covering galena. Galena is very shiny and on some faces, there are traces of beginning of desolvation process.
Beautiful and very aesthetic specimen presenting well-terminated galena crystals covered by quartz. Galena show clear signs of step growing.
