Karibib District, Erongo Region, Namibia
Light green translucent to transparent crystal pieces and cleavages. A few have purple zones. Some of them (maybe 25 percent) are fluorescent purple under shortwave and longwave ultraviolet light.
The pieces run from about 5mm up to about 3cm (1/4 inch to 1-1/4 inch). Perfect for tumblers, but only a 4 on the hardness scale, so they work best without a lot of harder minerals in the tumbler.
