Named "the king of garnets," tsavorite comes in an amazing green, ranging from fresh spring-green to deep forest-green. It is one of the world's most superb and beloved gemstones with limited availability.
Henry Platt of Tiffany & Co. jewelers launched tsavorite in the United States. He christened the gem after Tsavo National Park in Kenya. Its gorgeous green shades can be a crisp green, vivid bluish-green or intense forest-green. Green tsavorite is a calcium-aluminum mineral and part of the grossularite branch of the garnet group. Tsavorite gains color from traces of chromium and vanadium oxide in the stone. What you see is what you get with tsavorite; no heat, oil or other form of treatment is needed to achieve this brilliant emerald green. Two decades after its discovery, tsavorite is considered one of the world's most gorgeous, prized and sought after gems. Similar to demantoid garnet, there is a shortage of tsavorite garnet, and, therefore; it is hard to find. Its availability is not certain in the near future.
Campbell R. Bridges, a renowned Scottish geologist, first discovered tsavorite in Tanzania in 1967. Bridges later found a second deposit in the Tsavo region of Kenya in 1971. Tanzania and Kenya remain the two main mining sites for this gem. Four mining operations supply the global market. We obtain tsavorite from Block D of the Karo Mine, located in the Arusha region of Tanzania. This mine is also home to our tanzanite supply.
