The 10 Most Exquisite and Extravagant Tiaras in European Royal Vaults

Catherine, the Duchess of Cambridge, wore the Lotus tiara to her first-ever official state dinner in London in October 2015. She also wore the piece to a 2013 white-tie event at Buckingham Palace. The tiara came to Kate via Prince William's great-grandmother, the Queen Mother. It was originally a necklace given to the Queen Mother from King George VI in 1923. He had the necklace remade into a tiara, which was given to Princess Margaret and, later, Queen Elizabeth.
