Beautiful specimen of skeletal Galena cluster decorating attractively Quartz plate with 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 Galena cubes are with parallel truncated corners. The faces are matt lustrous. Yellow Chalcopyrite crystal of 15 mm adds a nice accent. In excellent condition – some small nicks. On acrylic base.
Fascinating specimen from this closed mine – the only one that makes these structures!
