The specimen comes with a previous label from the collection of Ray DeMark.The Rubtsovsk Mine, located in the Altai Krai region of southwestern Siberia, Russia, is part of the metal-rich Rudny Altai polymetallic belt. Geologically, the deposit sits within complex Paleozoic volcanic and sedimentary sequences where hydrothermal activity and extensive supergene oxidation created rich zones of secondary mineralization.
