An extraordinary 1920s Art Deco marquise-shaped ring hand-crafted in solid platinum, featuring a prominent 30 x 15 mm openwork plaque.   

At the center sits a brilliant cushion-cut blue sapphire (6 x 5.5 mm) encased in a smooth collet bezel setting. The intricate geometric plaque is set with a rich array of natural diamonds: 4 Old European cuts, 14 single cuts, and 78 accent rose-cut diamonds (16 surrounding the central ring, 4 accenting the inner geometric borders, and 58 lining the outer frame). The entire setting is elevated on a light, airy openwork gallery that maximizes brilliance.
