On Monday, 19 Sept., Middleton, who recently received the new title of Princess of Wales, arrived to the queen's state funeral at Westminster Abbey in the same four-strand pearl choker that she wore to Prince Philip's funeral last year, and to the late couple's 70th wedding anniversary celebration at Windsor Castle in 2017. The necklace — which was styled with Bahrain pearl drop earrings that also belonged to the queen — was lent to Princess Diana on occasion, and is reportedly made of pearls gifted to the queen by the Japanese government in the '70s.
