A versatile and beautiful piece of Art Deco history. This style ring has a hinged center which allows you to wear a stacked group of rings with a central row of rubies and 2 diamond bands on either side of it and a central row of sapphires with 2 diamond bands on either side of it as well. No detail was missed on this ring. Even the the edges of the platinum bands have been beautifully engraved. You have a comfortable stack without having separate rings! How very clever. Ring is sized at 5.5 and cannot be resized. Not marked but tested platinum. An independent gemological appraisal will accompany this ring at purchase. A classic that never goes out of style.
