Sally Agarwal

London-based designer Sally Agarwal uses softly tumbled, unfaceted polki diamonds in her debut collection. Such stones were used in India, where Agarwal studied jewelry design for many years, for traditional ceremonies in the royal courts. The gems glow in Agarwal’s rose-gold drop earrings ($4,800), layered necklace ($29,000), and three-strand bracelet ($20,000). (
