3. At the wedding of Lady Charlotte Wellesley (daughter of the Duke of Wellington) on Saturday, the Duchess of Cornwall piled on major (if strangely matched) jewelry: her pearl necklace with the large diamond clasp, her diamond Magic Alhambra earrings by Van Cleef and Arpels, her enormous diamond engagement ring, and a large gold bracelet. (Unfortunately, the bride wore no jewels at all. Boo!)
