A superb specimen of skeletal galena and chalcopyrite 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 amazing terraced structures. The faces are matt. Yellow chalcopyrite crystals and black sphalerite intergrow with the galena. Small quartz crystals are seen too. In very good condition – some small nicks and contacts. On acrylic base.

Pretty!
