3.02 Carat GIA Cert Cushion Cut Diamond Platinum Engagement Ring circa 1920s


Amazing diamond & platinum engagement ring. Features a gorgeous over 3-carat cushion cut diamond that comes with a GIA certificate (see picture 10) stating that the diamond is G color and SI1. The setting is made of platinum and set with round faceted diamonds. The ring is size 6.75 and can be re-sized. The diamond is old cushion cut, very lively and sparkly, it has some magic! It is one-of-a-kind stone that was hand-cut about a hundred years ago.
