Brucite Locality: Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa (Locality at mindat.org) Size: 7.5 x 6.2 x 4.0 cm. Wavy, curving crystals of brucite with intense blue color - very rare for the species and classic for this mine. This is a superb, robust example, with great display aesthetics. Crystallized brucite is actually quite rare, known from just a handful of localities. For my taste, these are the prettiest for sheer color. Ex. Charlie Key. Mineral
