Platinum Diamond Solitaire Ring 0.70ct

A platinum diamond solitaire ring featuring a round brilliant cut diamond of approximately 0.70 carats, S colour, SI1 clarity. The stone is held in a distinctive coronet mount with scalloped petal-form claws that give the setting an almost floral quality when viewed from the side.
Small rose-cut diamonds are set into each shoulder, adding subtle detail to the tapering platinum shank. The combination of the high coronet setting with rose-cut shoulder stones is characteristic of French workshop production from the Art Deco period, and the construction and wear here look consistent with that dating.
