Vintage .31 Retro Diamond Engagement Ring in 14k Yellow Gold.  This ornate engagement ring comes to us from the Retro era and is finished in 18k yellow gold with 14k white gold prongs holding the Old European cut diamond. The band is full of wonderful puffy engravings that are accented by small diamonds. This ring was made as a set with a wonderful matching wedding band we currently have in stock! A fabulous one-of-a-kind piece that is full of historic charm.
