A beautiful specimen of galena, chalcopyrite, sphalerite and 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 an amazing terraced structure. The faces are matt lustrous. The galena cubes are with parallel truncated corners. An attractive decoration is yellow chalcopyrite crystals over an isolated black sphalerite cluster. Small quartz crystals form the base. It displays beautifully all over 360 degree. In excellent condition – some small nicks.
Fantastic!
