The exhibit is packed with head-turning sparklers from the French design house, many of which have been worn by timeless beauties such as Elizabeth Taylor and Princess Grace. The stylish crowd, which also included Vera Wang, Kelly Rutherford and Chelsea Clinton, perused the exhibition before enjoying a five-course meal by celebrity chef Jean-Georges Vongerichten. Wang summed up why diamonds really are a girl’s best friend: “I’ve always been a jewelry girl," she told us. "Wear them with a T-shirt, bathing suit or an evening gown. It just works!” The exhibit will be open to the public February 18th through June 5th. See more celebrities at the gala in the gallery. — Randy Miller
