Tsavorite
A Variety of Grossular Garnet
Ca3 Al2 Si3 O12

Tsavorite is a variety of green grossular garnet discovered in 1967. It is one of the newest of the precious gemstones.

It is often compared to emerald, but in many ways, tsavorite is a superior choice. It occurs in shades of green ranging from spring-like pale green to intensely bluish green to deep forest green. It 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.
