Tourmaline is the name of a large group of boron silicate minerals. These minerals share a common crystal structure and similar physical properties - but vary tremendously in chemical composition.
The color of tourmaline is caused by the presence of different trace elements in the mineral. The most common color-causing elements are iron, manganese, chromium, copper, and vanadium. Iron: Iron can produce green, blue, and black tourmaline. Manganese: Manganese can produce pink, red, and yellow tourmaline.
