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.
