Jacobsite Locality: Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa (Locality at mindat.org) Size: miniature, 5 x 4 x 3.25 cm JACOBSITE with crystals to 6mm BRIGHT crystals that are so sharp and lustorus you would think them to be magnetite...for quality, amazing for the species. Additionally, for both isolation and aesthetics, this is a superior miniature display specimen of the species. Taken together, Charlie felt this was the finest example he had seen in his decades in South African mineral dealing. Mineral
