Killer specimen of skeletal Galena sprinkled by Chalcopyrite 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 other forming amazing terraced structures. The faces are matt lustrous. Attractive decoration is yellow Chalcopyrite and Pyrite growing above. In excellent condition – some small nicks.
Exceptional specimen from this closed mine – the only one that makes these structures!
