9th Septemvri mine (Deveti Septemvri mine), Madan ore field, Rhodope Mts, Smolyan Oblast, Bulgaria
Killer skeletal Galena decorated by Quartz from 9th Septemvri mine, Madan ore field, Bulgaria. Very attractive 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. Some small Quartz crystals enrich the display. In good condition – some nicks and contacts., Exceptional specimen from this closed mine – the only one that makes these structures!
