This vintage Art Deco cocktail ring features a 1.67 carat cushion-cut blue sapphire in a bezel setting with platinum filigree and milgrain details. The square-shaped design highlights the center sapphire while also including F color, VS2-SI1 clarity natural diamonds with a combined weight of 1.72 carats in old European, old Mine, and single cuts (four at 4.25mm/.33 carats each and two at 2.0mm/.03 carats each). The platinum band has a chevron pattern engraving that adds more detail to the overall design.
