At the AGTA show, Bridges said the tsavorite (figure 7) could be a once-in-a-lifetime stone. Despite seeing most of the finest tsavorites in the world above 20 carats, he had never seen one comparable to this size in a square cushion cut. The square cushion and round cuts are the rarest shapes for tsavorite because the rough typically lends itself better to other shapes. Square cuts in particular result in the greatest loss of weight in cutting, he said. The tsavorite also has the distinction of being the largest tsavorite, and the largest gemstone of any kind, cut in the United States.
