A cool specimen of skeletal galena, chalcopyrite, pyrite, sphalerite and quartz from 9th Septemvri mine, Madan ore field, Bulgaria. It displays a very neat and geometrical arrangement of stacked and aligned galena crystals overgrowing each other. An 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 lustrous. Yellow chalcopyrite crystals and brassy pyrite with a strong luster are seen too. Black sphalerite and quartz crystals enrich the display. In excellent condition.
