Tsavorite or tsavolite is a variety of the garnet group species grossular, a calcium-aluminium garnet with the formula Ca3Al2Si3O12. Trace amounts of vanadium or chromium provide the green color.
The colors of tsavorite garnet range from pale green to deep forest green and can sometimes rival high quality emeralds. With a hardness of 6.5-7.5 on the Mohs scale tsavorite garnet causes no problems at cutting, setting and wearing. It is well suited for invisible settings, where stones are set closely joined.
