Tourmaline

Maine designated tourmaline as the official state gemstone in 1971. Tourmaline ranges in color from black or white to vibrant shades of red, green, and blue. Individual crystals can be opaque to transparent and may be single or multi-colored.

The best Maine tourmalines rival tourmaline from world-famous locations in California, Brazil, and the Himalayas. The crystals range in size from microscopic to over a foot long.
