Tsavorite

Tsavorite was discovered by British geologist Campbell R. Bridges in 1967 and named by Harry Platt of Tiffany & Company (New York) who immediately recognized its potential due to its gemological pedigree and named it after the Tsavo Game Reserve in Kenya, the area of its discovery. Though tsavorite is found in both Tanzania and Kenya, the very finest tsavorite, with the purest green hues is still only found in Tsavo, Kenya. It is also colloquially referred to as green garnet.

The Smithsonian gem collection’s prize tsavorite is just 7 carats. The largest, cleanest tsavorite on record is a 325.14 carat top-color beauty and is valued at over USD$2 million.

Tsavorite has earned its place as one of the world’s finest coloured gemstones. Its high refractive index and dispersion levels translate into wonderful brilliance and it is far less include than its cousin, Emerald. Its stunning, pure green hues, durability, purity and rareness have attracted gem collectors and jewelry lovers alike.
