Chrome tourmaline is a rare variety of green tourmaline, colored by chromium and vanadium. This material from Tanzania is known for its rich, saturated green with excellent clarity.
Tourmaline is a boron silicate mineral that forms in pegmatites and metamorphic rocks. Chrome tourmaline is distinct from standard green tourmaline due to its higher chromium content, giving it a more intense, emerald-like color.
Tanzania has been a key source of fine chrome tourmaline. Proper cutting maximizes its brilliance and strong pleochroism
