What an amazing and unique ring! The platinum, square dome shaped top, set with single cut diamonds and milgrained edges give the ring a very Art Deco feel. Although, from the stamp on the outside of the shank we know the ring is Russian and made sometime after 1965! The top of the ring is finished with a beautiful small cabochon blue sapphire. To add to the uniqueness of the ring the under gallery and shank of the ring are rose gold! The finish and all of the details on this ring are exceptional! This is sure to strike up conversation no matter where it's worn, it's one of our favorites!
