Nice octahedral Hausmannite crystals from the famous Kalahari manganese fields, South Africa. They are sharp with multiple stepped striations. The crystals have black color and strong metallic luster. Unidentified white minerals is seen too. The world’s finest Hausmannite comes from the Kalahari Manganese Field and this one is a pleasing specimen. Some contacts. On acrylic base.
Good Hausmannite!
