Fascinating specimen of skeletal Galena decorated attractively by Chalcopyrite from 9th Septemvri mine, Madan ore field, Bulgaria. 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 structure. The faces are matt lustrous. Yellow Chalcopyrite crystals up to 20 mm add a nice accent. Colorless small Quartz crystals are seen too. It displays all over 360 degree. In very good condition – some small nicks and contacts. On acrylic base.

Marvelous specimen from this closed mine – the only one that makes these structures!
