Cabinet, 9.4 x 6.4 x 3.4 cm
Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa

A rich specimen of gemmy, bright yellow ettringite crystals scattered liberally across the matrix. The pic is a bit overexposed and makes them look a bit washed out, but in person they are quite a pretty yellow, with nice luster and much more gemminess than the pics show. 9.4 x 6.4 x 3.4 cm
