Middleton, too, was loaned the four-strand choker to celebrate Queen Elizabeth II and Prince Philip, Duke of Edinburgh's 70th wedding anniversary at Windsor Castle. Middleton let the jewels shine, wearing the necklace with a black lace dress and pearl drop earrings next to Prince William, who also arrived in black tie. Middleton wore the design one more time, for the funeral of the Duke of Edinburgh in April 2021.
