An Excellent specimen of large galena crystals on the tick galena base. Crystal forms are a combination between cubs and octahedrons, and in some parts could be seen the skeletal development of the octahedron faces. some shiny black sphalerite crystals are fallowed
An interesting specimen presenting very well shaped cubic galena crystals singenetically developed with black sphalerite on quartz. The surface of galena, shows specifical step growing patern.
A large galena crystals on quartz with sphalerite. Galena is slightly dissolved and covered by small, lustrous cubic pyrite crystals.
A very interesting specimen build of quartz, followed by galena particularly corrupted and exchanged by chalcopyrite, which also is dissolved in some parts by recrystallizing pyrite
A beautiful small specimen showing a very shiny and well-terminated sphalerite(marmatite) crystal. It combines developing of several crystals on the surface of one tetrahedral sphalerite crystals – forming „sphalerite star“.Marmatite is fallowing quartz long axes quartz crystals
This specimen presents one phenomenon of developing of some galena crystals in „9-th of September mine“ – Madan. Spyral, step growing of galena forms crystals looking like result of building activities.Galena overgrought sphalerite and quartz
An exceptional lustrous specimen of galena with well shaped mosaic faces, in genetically developed with sphalerite and quartz.
The excellent sample of skeletal developing of galena crystals, on the top of sphalerite and quartz.
Extremely shiny and well-developed galena crystals overwrought by sphalerite and pyrite, followed by thin transparent quartz crystals
An aesthetic specimen presenting pyrite and galena developed on mother rock, followed by very well shaped sphalerite(marmatite0 shiny crystals, covered by rhombohedral crystals of calcite
