When the man behind de Grisogono, Fawaz Gruosi, introduced his striking black diamond jewelry combined with rubies, emeralds, sapphires, and white diamonds, industry veterans called him crazy. “Everyone told me that black diamonds would never sell because people expect diamonds to be white,” recalls Gruosi. Obviously, they were wrong; black diamonds are now widely employed in high-jewelry designs. Signature Style: Exceptionally large rubies, emeralds, and sapphires shown in elaborate and sexy chokers, drop earrings, and bold rings, and innovative use of diamonds and stones in unexpected combinations such as emeralds with turquoise.
