Chrome tourmaline is a rare type of dravite tourmaline. Due to the presence of chromium and vanadium in the crystal structure the color appears 'chrome' green. Chrome tourmalines are unique in the tourmaline group, because they are mined in only one country in the world, Tanzania.

All natural chrome tourmaline gemstones are crafted to the most precise specifications and uniformed in terms of brilliance, color, clarity, dimensions and shape. To offer maximum consistency and quality, all rough chrome tourmalines are sourced from our own mines or from the most reliable suppliers in the industry.
