Brucite, Sturmanite
Miniature, 5.0 x 3.2 x 1.4 cm
Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa
A very good plate of botryoidal, sea-foam green-blue Brucite, with a trace of non-crystalline Sturmanite. The radial crystals of Brucite that make up the botryoids are up to about .7 cm long, and in places the crust is nearly 1 cm thick. An excellent specimen for the species. Ex. Charlie Key.
