MT Yogo Sapphires

The Montana “Yogo” sapphire is a specialty at Chalet. They are the only sapphire of its kind and quality in the world. Found only in central Montana in the Little Belt Mountains near Lewistown, the majority of Yogo sapphires come in a gorgeous, vivid blue color, with a small percentage in a beautiful lavender color. Because of the Yogo sapphire’s intense natural color, they never require heat treatment to enhance the color. The Yogo sapphire crystals are typically very small and very flat and large stones of gemstone quality are very rare. This is what makes them unique and valuable!
