- Schorl, Opal (Var: Opal-An)
- Cabinet, 10.8 x 8.0 x 3.0 cm
- Erongo Mountain, Usakos and Omaruru Districts, Erongo Region, Namibia
Absolutely one of the finest Schorl specimens I have ever seen from the Erongo Mountains. Every single crystal in this large 10 cm plate has superb luster and incredibly sharp form. It is even complete-all-around, though covered with hyalite opal on the backside. The crystals range from .5 cm up to 2.5 cm. Ex. Charlie Key.
