A striking 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. Black sphalerite and chalcopyrite are seen too. In good condition – some small damages. On acrylic base.
Superb piece from this closed mine – the only one that makes these structures!
