1.86" Black Tourmaline (Schorl) - Namibia

This is a great cluster of schorl and quartz from the Erongo Mountains in Namibia. It appears that there is only one natural break, though otherwise this is an very nice specimen with great luster, and many 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.
