Precious gemstones are found in many exquisite antique engagement rings. You may already own a vintage ring with one or more precious gemstones, including sapphires, rubies or emeralds. Some of the more coveted gemstones are the Kashmir, Burma or Ceylon sapphires, the Burma ruby, and the Columbian Muzo emerald. Precious gemstones add a nice splash of color to an original art deco engagement ring. Please keep in mind, while sapphires are traditionally known to be blue in color, they may also be pink, yellow or green!
