When it comes to standing out on the red carpet, Hollywood's elite turns to Neil Lane. Known for his one-of-a-kind diamond creations, the L.A.-based jewelry designer is currently a Brand Ambassador for DeBeers, a job he describes as a lot of "parading around." This elegant, Edwardian "festooned" piece, which is part of a necklace-and-earring set, includes 175 EDF flawless white diamonds for a total of around 50 carats. Throw in another 5.63 carats per earring, set it all in platinum, and she'll definitely be ready for her close up!
