The stunning vintage Art Deco style ring dates to the 1920s and is a size 6. It would be a beautiful engagement ring. It is made of 18k White Gold and features a stunning octagonal .4 Ct. Diamond. The setting is Basket style with a bezel setting to secure the diamond as well as 4 additional prongs for added security. The face of the ring is 10 mm wide. There is delicate filigree on the face of the ring. The sides of the band are beautifully engraved but it does not continue around the entire band so it could be sized by a good jeweler. The ring weighs 2.7 grams. Please take a moment to review the photos and take a look at the other Art Deco 1920s pieces in my shop. I update items frequently.
