Incredible Art Deco Diamond Engagement Ring in Platinum.  This beautiful Art Deco engagement ring features a 1.27 carat Old European cut diamond set in platinum. The many details on the mounting are ornate and fabulous, with the filigree work lifting up the center stone in a smooth curve with lovely open spaces adding further dimension. From the side profile you can see the neatly placed parallel filigree wires, which speak to the careful craftsmanship of the time. The high quality center stone is bezel set with milgrain detail to bring out every bit of sparkle and complete this work of art.
