9th Septemvri mine (Deveti Septemvri mine), Madan ore field, Rhodope Mts, Smolyan Oblast, Bulgaria
Neat skeletal Galena specimen from a new find in this closed mine - 9th Septemvri mine, Madan ore field, Bulgaria – the only one that makes these structures. The skeletal structure is caused by very fast growth of the mineral where the crystal faces do not have the time to be completed because the edges grow faster than the center. Displays very attractive stepped growth, forming gorgeous terraced structures on all faces. The Galena cubes are matt lustrous and light reflective. They are well formed. On the Galena are seen small Quartz crystals proving the natural origin of the skeletal structures. In good condition – some nicks and contacts., Cool skeletal Galena!
