7. Kate Middleton
Kate's ring looks different than her sister Pippa's, no doubt, but we love both the same. Kate's carries some extra value too, as it's the same ring Prince Charles gave to Princess Diana, Will's late mother. It's a 12-carat sapphire with a halo of exactly 14 diamonds. The original ring was valued at $47,000, but with the diamond upgrades, is now worth $500,000.
