History of Montana Sapphire and Diamond Ring

Montana sapphires were first discovered in the mid-19th century by gold prospectors. These gemstones are famous for their unique 'teal' or 'steel blue' colors, which are rarely found in sapphires from other global deposits like Sri Lanka or Myanmar. This specific multi-stone setting became a staple of American fine jewelry in the late 20th century, celebrating domestic gemstones.
