Tsavorite is a trade name for the emerald-green variety of Grossular Garnet that originates in Africa. Tsavorite has become one of the most popular and expensive Garnets, due to its rarity combined with effective marketing tactics. This gemstone was first discovered in Tanzania in 1967. It was subsequently found in the same geological formation across the border in Kenya in 1970 near Tsavo National Park, a wildlife preserve in the African Serengeti, and given its name after the national park. Tsavorite was named by both Campbell Bridges, the discoverer of Tsavorite, and by Henry Platt, the president of Tiffany & Co. (one of the world's largest jewelry companies). There are a number of locations along the Tsavorite belt where this beautiful gemstone is mined, but there is only one area which produces a very rare colour of Tsavorite containing a hint of blue. This is considered the ultimate colour in Tsavorite and a very few stones are mined every year from this deposit. The cause of the superior colour is a touch of Chromium in the ground along with Tsavorite’s normal colouring agent – Vanadium. This place is called Kuranze and Tsavorites mined from here are much coveted for their quality. Tsavorites are not generally available in large sizes. Even 1 carat fine stones are rare. On average, it takes over 1 ton of gem bearing rock to extract under 5 carats of fine 1 carat pieces. Fine stones over 2 carats are rare and over 3 carats they become very rare in the fine qualities.
