A superb 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. The corners are truncated and parallel. Yellow chalcopyrite forms the base and small brassy pyrite cubes grow in it. Black sphalerite and quartz crystals enrich the display. In excellent condition. On acrylic base.
