Tsavorite, The World’s Rarest Garnet

A stunningly beautiful green gemstone that rivals any other green gem. Stones with deeply saturate pure green color will command the highest prices. 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. TSAVORITE IN JEWELRY Tsavorite has a rating of 6.5 – 7.5 on the Moh’s scale of gem hardness and is therefore very durable and suitable for all forms of jewelry. Due to its high refractive index and high dispersion levels, makes this stunning green gemstone is incredibly sparkly and eye-catching, they really 'pop' when set with Diamonds, as they too have a high refractive index and really compliment each other. Enhancements Normally, these gemstones don’t receive any treatments or enhancements, which makes them very desirable to collectors and enthusiasts of natural gems. Sources Commercial sources for gem-quality tsavorites include Tanzania, Kenya, and Madagascar. Small deposits also occur in Pakistan and Queen Maud Land, Antarctica. Sizes Clean tsavorites over one carat are rare. However, in 2006, a crystal weighing 925 cts (185 g) was discovered in Tanzania. It yielded an oval, brilliant step-cut 325-ct gem, likely the largest clean specimen ever discovered. Care Although generally clean, some tsavorites do contain inclusions. Gems with fluid inclusions shouldn’t be cleaned with mechanical systems or exposed to extreme heat. Instead, use warm water, detergent, and a soft brush. (This advice applies to garnets in general)
