Tsavorite garnets on graphite matrix!From Merelani Mine, Arusha, Tanzania. Credit: Anton Watzl Chrome grossular is a green variety of grossular. Tsavorite (or tsavolite) is a grossular that, like the Meralani mint, is green in colour. It is coloured by chromium and/or vanadium. The distinction between a 'regular' green grossular and tsavorite is commonly thought to be a function of saturation and tone.
