Montana Sapphire 0.405ct Loose (Green Sapphire)
Montana sapphires began when Dr. J.F. Kunz, a vice president of Tiffany & Co., proved that blue rough stones found in Yogo Valley, Montana, were sapphires. There are several deposits, and the tendencies vary from place to place, but they are generally characterized by high transparency and the fact that many fancy colors are produced. This is a 0.405ct loose Montana sapphire with a high transparency and a distinctive green color.
