Tourmalines have a variety of exciting colors with one of the widest color ranges of any gem.
Why we love this gemstone
Tourmaline crystallizes in the trigonal system; no other common mineral has three-sided prisms.
Watermelon tourmaline is green on the outside and a delicious pink on the inside.
Liddicoatite tourmaline was named for beloved former GIA President Richard T. Liddicoat.
