René Boivin Sapphire “Feuille” Brooch

Created in the late 1930s by Van Cleef & Arpels Paris, this Burma sapphire and diamond ring is mounted in platinum. The ring centers three vertically-set cushion-cut sapphires, weighing 1.96, 1.21, and 1.20 carats, flanked by two canted rows of calibré-cut sapphires mounted on either side of an domed step, and arched shoulders set with graduating round-cut diamonds. Densely set with royal blue Burma sapphires, and rich in artistic impact, this streamlined masterpiece by Van Cleef & Arpels is a statement of sculptural monumentality in miniature.
