What is Tourmaline?

Tourmaline is a crystalline silicate mineral group with a general chemical formula that varies widely due to isomorphous substitution involving elements like aluminum, iron, magnesium, sodium, lithium, potassium, and others. This chemical complexity allows tourmaline to exhibit nearly every color imaginable, making it one of the most diverse gemstone groups.

Formation and Sources

Tourmaline forms in igneous and metamorphic rocks, often in pegmatites and hydrothermal veins. It is found worldwide, with notable sources including Brazil, Afghanistan, Madagascar, Nigeria, and the United States.
