This is a gorgeous, polished stalactite end-cut of rhodochrosite from the famous Capillitas Mine in Argentina. The face of this specimen has been polished to a mirror-like finish, with the back side of the specimen remaining rough and in its natural form. A large section of the exterior mineralization has been broken away from this specimen. The edge of this specimen has been cut flat, allowing for aesthetic presentation without the need for a display stand.
Rhodochrosite is a manganese carbonate mineral with them chemical composition MnCO3. The crystals typically have a pink-red coloration and cleaves with rhombohedral cleaving in three directions. It forms from hydrothermal pockets and can be found as both crystals and in banded formations.
