Killer plate of skeletal Galena decorated with Sphalerite and 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 another forming amazing terraced structure. The faces are matt lustrous. Dark Sphalerite crystals and yellow Chalcopyrite grow above. Displays on both sides. In excellent condition – some small nicks and contacts.
Exceptional specimen from this closed mine – the only one that makes these structures!
