Maine is famous for Tourmaline, and it is the official Maine State Mineral.
Tourmaline is a group of similar mineral species varying in composition and color.
Two species of the tourmaline group are widespread in the igneous rocks of southwestern Maine.
Schorl is a black iron-rich variety, and by far the more common of the two.
Elbaite is a lithium-bearing tourmaline that forms beautiful crystals in pink, green, blue, or combinations of these colors.
