Beautiful skeletal Galena cluster decorating attractively Quartz plate with Sphalerite and Chalcopyrite from 9th Septemvri mine, Madan ore field, Bulgaria. Very neat 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 Galena cubes are with parallel truncated corners. The faces are matt lustrous. Black Sphalerite and yellow Chalcopyrite are seen too. In very good condition – some nicks and contacts.
Gorgeous specimen from this closed mine – the only one that makes these structures!
