Black tourmaline and smoky quartz on albite matrix with hyalite Coprolite and a faint phantomLocale: Erongo Mountain, Namibia Approx dimensions: 4. 5 x 4 x 1. 5" Approx weight: 728g (1. 6 lbs) This large specimen is one of my favorites of the Erongo black tourmaline, known as schorl. The piece is a rough aggregate of minerals appearing to contain albite, schorl, and smoky quartz. The front is nearly entirely covered with dozens of blocky small schorl crystals, some displaying the Mercedes termination characteristic of the Erongo region.
