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.
I faceted this tsavorite in a custom square design created by the late Jeff Graham; the design is called “Lighthouse.” It weighs 0.62 carats and measures 4.9 x 3.5 mm. The color is a intense rich green, appearing much more green with blue tones than the photo implies. There are some minor inclusions typical for this species of garnet, but they are not visible without a loupe–its an eye clean gem.
