.70 Art Deco Diamond Engagement Ring in Platinum.  This GIA-certified, Art Deco engagement ring features a .70 carat Old European cut diamond in platinum. The shimmering center diamond has a beautifully soft champagne hue, bringing a touch of warmth to contrast the cool tone of the shimmering platinum band. The primary diamond is flanked by twelve .018 carat accent diamonds that are near-colorless in a boxy, Art Deco step mounting. The mounting features soft milgrain details in between the accent stones and has an openwork gallery that elevates the diamonds slightly above the platinum band. This engagement ring is structured and elegant, and can be easily resized upon request!
