Vintage Art Deco Cocktail Ring w/ Diamonds in White & Rose Gold. This wonderful Art Deco ring features .71 carats of Old European cut diamonds set in 14 karat white gold over a 14 karat rose gold band. The mounting is made of an intricate lattice of intersecting lines of milgrain edges and open spaces. The geometric design allows for neat spaces each diamond can sit in their prong setting. The rose gold shank provides a nice contrast against the icy white face of the ring and completes the look of this stunning vintage piece.
