What is Black Tourmaline?

Black tourmaline, or schorl, is the iron-rich and most common member of the tourmaline group. It grows as long prisms with deep lengthwise grooves (striations) and a triangular cross-section.

It is supplied as rough pieces, natural crystals, polished towers and beads, and is one of the best-selling protection stones worldwide.
