In this specimen we can enjoy a rich group of lenticular sturmanite crystals orange, bright, with a yellow to orange color, transparent and with very sharp faces and edges. It is accompanied by rosettes of greenish brucite, a magnesium hydroxide. In the same specimen there are two very interesting species for systematic and aesthetic collectors.

Most people do not know that these come from anywhere but Utah, but here is a Kalahari Manganese fields bixbyite specimen. A druse of highly lustrous, very sharp interpenetrated cubes of black bixbyite from this famous locality. An excellent specimen for the locality. A true rarity.
