Antique Engagement Ring Art Deco .89 Round Brilliant Cut Diamond in PlatinumThis Art Deco Era engagement ring has all of our favorite elements of a piece from this era. A . 89 carat diamond is box set in the center with triple prongs and is cast in Platinum. The sides are beautifully done with a three (3) marquise shapes each holding a single diamond and then a row of four (4) diamonds running vertically along the center diamond.
