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
