Dating from circa 1900, this ruby and diamond ring is set in platinum and 18K gold. It is bezel-set with an untreated Burma cushion-cut ruby, measuring approximately 8.05 x 7.65 x 3.95 mm, and weighing approximately 1.85 carats, framed by a stepped surround of old mine-cut diamonds, and flanked by diamond shoulders in a fleur-de-lis motif, set in platinum-topped 18K gold. With its forward-looking geometric design, this beautifully colored and gracefully shaped gem ruby sits in a delicate Edwardian mounting that balances lightly on the hand.
