JAR bracelets are renowned for their sculptural forms, which transform the wrist into a canvas for intricate botanical compositions. Flower bangles such as the celebrated ‘Parrot Tulip’ and ‘Apricot Blossom’ reveal Joel Arthur Rosenthal’s ability to render precious materials with the softness of fabric, using diamonds and coloured gemstones to define individual petals. Other creations draw on historic ornament, with richly coloured surfaces extending around and beneath the wrist. Oxidised titanium, blackened silver and unconventional gemstone combinations lend depth to his designs, while meticulous pavé work brings texture and dimension to each jewel.
