This is a gorgeous vintage Aquamarine ring done in platinum. The beautiful light blue aqua is estimated at .90 carats. It is securely set by 4 prongs. Then there are 2 diamonds on each side shoulder. Total diamond weight is estimated at .10 carats. The diamonds are at least SI quality. with tons of sparkle. It is 6.08mm wide North South. The ring is stamped for platinum & another stamp but I don’t know what the symbol represents, probably the manufacturer. The finger size is 4.5 & it can be sized. It weighs a heavy 3.6 grams, a solid weight. This is a beautiful ring, the design is fabulous & striking. The ring is in good condition & ready to wear. Aquamarine is the birthstone for March. This would make a great gift for a March girl or this could serve as an engagement ring or a right hand ring, very pretty. I have been selling jewelry for two decades.
