Quartz, Orthoclase
Erongo Mountain, Usakos and Omaruru Districts, Erongo Region, Namibia
Cabinet, 10.5 x 8.5 x 8.0 cm
An outstanding single, doubly-terminated Quartz crystal the likes of which I have not seen from the Erongo region. This giant 10.5 cm crystal is perfectly gem-clear, with a glass-like luster. It looks like a topaz and I would be fooled if not for the hardness test we did on it. The termination is complexly etched by solution effects. Ex. Charlie Key.
