Tsavorite is actually a green garnet that, given its rarity, is commonly considered a different gem altogether. It's a very brilliant genuine gemstone whose strong green color makes it an attractive option for your Class Ring Mod™ centerpiece.
Tsavorite is often facetted when cut and has a hardness rating of 6.5 to 7.5 out of 10. A class ring with a tsavorite centerpiece can be worn daily with proper care.
