    Figure \(\PageIndex{1}\)

    Tri-color tourmalines come in just about every variety of color. Tri-color or multi-color tourmaline usually has 3 or more predominant colors present in the stone. Due to the fact that tourmaline are dichroic, they can appear to display many different colors all at the same time.
