It may not have the flash of a diamond but Tsavorite, a form of green garnet, has its own charms. The gem, which was originally discovered in the Tsavo region of Kenya, has a bright green hue that makes it a popular choice for those who like emeralds but want stones with a bit more fire. Tsavorite is rarely found in large clean stones which explains the preciousness of the 325.13 carat stone shown here. National Jeweler reports that Michael Coach and Associates has acquired the largest clean Tsavorite in the world and will be showing it at the American Gem Trade Association GemFair beginning at the end of January in Tucson, Ariz. The stone was found in the Karo area of Mereloni, Tanzania and from one rough stone four stones were cut: a 62-carat clean, a 120-carat clean, a 307-carat included and the 325.13-carat clean. The asking price for the gem is $2.2 million. It seems to be that a stone like this deserves a name like the gobstopper diamonds get. Is Jolly Green Giant too undignified?
