Tsavorite Garnet Gemstone Information
Tsavorite is a member of the Grossular Garnet group. All garnets belong to the Garnet group of minerals which is split in to two main groups. Tsavorite varies in color from yellow green to bluish green. Trace amounts of Vanadium & Chromium are the causes of the color, the higher amount of these trace elements leads to the better colored gemstones . The tremendous forces of Nature which created Tsavorite also damaged most of the crystals so badly at the time of their formation that today it is usually only grains or fragments which are found. For this reason only in rare individual cases are large raw crystal of over 5 carats found, so a cut Tsavorite of more than two carats is a rare and precious thing. But then that is one of the special features of this gemstone, it can display its great luminosity even in small sizes.
Garnet is the birthstone for January.
Tsavorite Garnet History

Value of Tsavorite
It is less well known than Emerald. As it is gaining in popularity, it is a good investment. Stones rise in value over 1ct. A 2ct clean stone is very rare indeed!
Tsavorite is not heated or treated. Similar stones are Emerald, Peridot, other Garnets, tourmaline. Tsavorite stands out with its brilliance. With Tsavorite you know you are getting a totally untreated stone – no heat nothing. Where as, nearly all Emeralds are treated and new treatments are regularly discovered! Hugely underrated; it is a wonderful gemstone.
