Cool skeletal geometry for these Galena crystals from famous Madan ore field, Bulgaria. It displays stacked and aligned Galena cubes overgrowing each other. Excellent parallel growth of cubes and elongated tetragonal prisms on different axes. They consecutively grow one atop another forming amazing skeletal structure. The crystals are matt lustrous. Black Sphalerite tetrahedrons are seen too. Quartz crystals grow above and add a nice accent. In good condition – some small nicks and contacts.
Neat Galena!
