Tourmaline

Tourmaline is a complex composite with one of widest color ranges in mineral world. The most common color is black (of no value as a gem), but Tourmaline may also be pink, violet-red, brown, yellow, green, or blue. Tourmaline slabs with a pink center and green rim (or vice-versa) are known as “watermelon” tourmaline. In healing, Tourmaline is associated with the heart chakra.
