Green Tourmaline

Growth from the heart outward.

Green tourmaline is a color variety of Elbaite, a significant commercial species within the tourmaline group. Its green color comes from trace iron, chromium, or vanadium. Known as Verdelite in some markets, green tourmaline ranges from pale olive to deep emerald. Heat treatment and irradiation are common in the commercial gem market to improve or deepen color, and these treatments are considered acceptable industry practice when disclosed. Beyond Bohemian's material comes from two sources: raw specimens from Minas Gerais, Brazil, and crystal chips from Nampula, Mozambique.
