This Antique, Art Deco Era Aquamarine and Diamond ring is just so dreamy. The vintage Art Deco era mounting is made in platinum and has beautiful detailing and engraving on almost every surface of the setting. The center stone is 5.04 carat square step cut Aquamarine with a rich light blue color, and is accented with .09 carats total weight of diamonds on the sides of the setting. We think this would be the perfect gift for a March birthday.
