A Gorgeous Antique Blue Opal Diamond, Wedding Ring Band Art Deco, circa 1920. This beautiful antique ring holds a blue opal stone at center measuring about 3.5mm in diameter. There are sparkling white diamonds on either side. The setting is Art Deco period, circa 1920 and is composed of 14K yellow and white gold. Overall the ring measures about 5/16 inch long by about 3/4 inch wide from side to side. Ring Size: about 8 1/2 (could be resized by your jeweler or ask me about using mine before shipping). The ring dates to the Art Deco Era and is in lovely vintage condition with a nick on one diamond that I noticed under 10x magnification. A wonderful example of the Art Deco era.
