Excellent specimen of bright metallic Spinel Law twin Galena with Calcite from the famous Madan ore field, Bulgaria. It displays sharp well formed superb flat faces Galena twins with excellent brilliance and strong luster. The vertically crystallized rosettes form attractive structures. The spinel twins are thin stepped plates, staggered one after another with like tooled tips.  Some minor Calcite is seen too. In very good condition – some small nicks.
Beauty!
