Outstanding specimen of skeletal Galena from 9th Septemvri mine, Madan ore field, Bulgaria. Very attractive and geometrical arrangement of stacked and aligned Galena 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. The Galena cubes are with parallel truncated corners and are twinned. Small Quartz crystals form the base. It displays beautifully all over 360 degree. In excellent condition. On acrylic base.
Gorgeous specimen from this closed mine – the only one that makes these structures!
