This enchanting Edwardian antique engagement ring plays with geometry and subtlety. From the side, this enchanting antique engagement ring is a series of surfaces sculpted in platinum filigree. From above, it is a startling pool of light: a hexagon brimming with diamond. A 0.76 carat old style round brilliant cut diamond is prong set at the top in a mille grained surround. This diamond glows softly with the color of candlelight. Circa 1920.
