Imperial Garnet is a beautiful stone that can exhibit some color change or color shift properties. The main source of these is Africa and they are closely related to the Malaya Garnet which also exhibits some color change. These stones can have very fine needles in them that give the stones a silky look. Look for stones that are as large as possible because most of the rough is found as small crystals. Large stones are fairly rare and are prized among collectors. Colour ranges are from orange to purple to reddish orange.
