1.78" Black Tourmaline (Schorl) & Feldspar - Namibia

This is a sharp matrix of schorl crystals and feldspar from the Erongo Mountains in Namibia. Although it has broken away from the host rock, the crystal is in overall good shape, and has good luster, and natural terminations.

Tourmaline is a crystalline boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Schorl, or black tourmaline, is the most common form of tourmaline, and has been used for everything from jewelry to piezoelectric guitar pickups.
