Tsavorite Alternate Birthstone for May A Variety of Grossular Garnet Tsavorite is a variety of green grossular garnet. It is one of the newest of the precious gemstones discovered in 1967. It occurs in shades of green ranging from spring-like pale green to intensely bluish green to deep forest green. Often compared to emerald, tsavorite is a superior choice in many ways. Tsavorite is not only more durable than emeralds, it is also more highly dispersive and refractive. Tsavorites are not treated with oils or resins as emeralds typically are.
