A cute specimen of galena, chalcopyrite and sphalerite decorating attractively the quartz base from 9th Septemvri mine, Madan ore field, Bulgaria. It displays very neat and geometrical arrangement of stacked and aligned galena crystals overgrowing each other. Excellent parallel growth of cubes and elongated tetragonal prisms on different axes. They grow one atop another forming an amazing terraced structure. The faces are matt. Yellow chalcopyrite crystals intergrow by very neat manner with the galena. Transpiration, sharp and clear quartz crystals and small black sphalerites are seen too. In very good condition – some small nicks.

Pleasing!
