Maine State Gemstone
Tourmaline
Tourmaline ranges in color from black or white to vibrant shades of red, green, and blue. The color of the best Maine tourmalines rival tourmaline from world-famous localities in California, Brazil, and the Himalayas. Individual crystals range from opaque to transparent and may be single or multi-colored. There is even a "watermelon" variety with a green outer layer surrounding a pink core.
