Diamonds are definitely Naomi Campbell's best friend. The 46-year-old model, actress, and fashion icon looked positively regal as she walked the red carpet at the Chain of Hope's Gala Ball yesterday, wearing a stunning black gown and a head-turning diamond necklace.

Campbell, who appears in the hit TV show Empire, arrived at the charity event in a breathtaking floor-length gown. The intricate black dress featured an ornate beaded bodice and flowing train. The fashion icon paired the look with a simple black clutch and several pieces of stunning diamond jewelry, including a necklace that crisscrossed down over her chest. To complete the outfit, Campbell wore her hair pin-straight and opted for bold, sparkly eye makeup.
