Antique Deco Platinum Star Sapphire Baguette Diamond Ring 17.50ct GIA No Heat
An original Art Deco ring crafted in platinum, centered by an impressive approximately 17.50 carat double cabochon no-heat Ceylon star sapphire, accompanied by a GIA laboratory report. The stone displays a soft, even blue with a luminous, velvety body, framed by a finely executed halo of round brilliant diamonds. Graduating baguette-cut diamonds along the shoulders introduce a precise, geometric structure that is unmistakably of the period. The ring carries a substantial presence while maintaining a low, refined profile consistent with well-made Deco pieces.
