Tsavorite garnet is named for the Tsavo region of Kenya, where many of these amazing green garnets are mined. While first discovered in 1967 in nearby Tanzania, significant quantities of gem grade tsavorite garnets have only been found in parts of Tanzania and nearby Kenya. Tsavorite is a form of grossular garnet, colored intensely green by trace amounts of vanadium. Paler green specimens have been called “Merelani Mint” garnets after the Merelani region in Tanzania. Tsavorite garnets are typically small and gems over 2 carats are quite rare. This Tsavorite is quite large for the species, and exceptionally clean, appearing all but flawless under a 10x loupe.
I faceted this Tsavorite in a custom rectangle cushion design I call “Eureka;” in the hand this is a remarkably bright and scintillating gemstone, with visible dispersion adding to its beauty. It weighs 2.50 carats and measures 8.3 x 6.2 x 5.8 mm. The color is a intense bright grass green, appearing slightly more blue-green in daylight.
