Tourmaline has a complicated chemical formation. Its formation includes elbaite, schorl, uvite, liddicoatite, and buergerite. It is the most multicolored mineral type known, occurring in every color of the spectrum. Crystals are frequently color zoned along their length (bicolor, tricolor, particolor) or concentrically zoned (watermelon). Each colored tourmaline comes with its own chemical formations. Well known sites are in Pakistan and Brazil.
This schorl tourmaline (black tourmaline) specimen is extremely unique and saturated with rich color. The striations in this specimen bring it to life. I enjoy how it branches off into two segments within the single specimen.
