A cool specimen of skeletal galena, chalcopyrite, pyrite and sphalerite 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. Yellow chalcopyrite crystals and brassy pyrite with a strong luster are seen too. Black sphalerite crystals enrich the display. In excellent condition - some small contacts. On acrylic base.
Rich morphology!
