The garnet group of gemstones is one of the most important of gem groups. There are numerous varieties of garnet, ranging in color from bright red to vivid green and everything in between. Some of the more popular green garnets include demantoid garnet and tsavorite garnet, two of the most valuable garnets available today. Demantoid is a variety of andradite garnet colored by chromium and ferric iron, while tsavorite garnet is a type of grossularite colored by vanadium or chromium. Other green garnets include color change garnet, 'common' grossularite garnet and the exotic hybrid Mali garnet found only in the West African country of Mali.
