Liddicoatite is an uncommon form of Tourmaline, almost identical in chemical composition to Elbaite, but with a calcium atom replacing a sodium atom in its chemical formula.
Liddicoatite is a very colorful mineral. Colors include green, red, pink, purple, and and blue. White, colorless, black, brown, yellow, and orange colors also exist.
Crystals are frequently multicolored, containing two or more distinct colors. Liddicoatite may also have internal color zoning and banding. Some specimens are pleochroic.
