Green Tanzanite is a visually appealing stone with a deep green coloration. It shows strong trichroism, meaning it changes color depending on where you look at it from. It shifts between lime-green, dark green, and dark blue, creating a beautiful trichroic effect.

Most Tanzanite stones are heat treated to enhance their beauty. A chemical stimulant called Tanzanion is used to enhance its color.
