The Yogo Sapphire is one of the most sought after gems on Earth and many experts consider its unearthing to be the most important gem discovery of modern times. Generally regarded as the world’s finest sapphire, Yogos come out of the ground nearly perfect, and unlike other sapphires, do not require heat treatment to attain its stunning clarity and quality. Found only in Montana’s Yogo Gulch across a five-mile long and on average eight foot wide dike in the Little Belt Mountains, these stunning cornflower blue sapphires are made even rarer by the fact that today they can only be hand mined by the handful of families who hold mineral rights in this area.
