Quartz (Var: Smoky Quartz), Schorl
Cabinet, 10.9 x 3.4 x 2.4 cm
Erongo Mountain, Usakos and Omaruru Districts, Erongo Region, Namibia
A stunning, large crystal of smoky quartz from the Erongo Mountains, and distinguished by having schorl tourmaline crystals shooting through its interior. The crystal is doubly-terminated, and has a tabular crystal growing across one of its faces, making it even more interesting (seeing these two habits intergrown with one another on the same specimen, again very unusual for Erongo) .
