The 10 Most Exquisite and Extravagant Tiaras in European Royal Vaults

For her 2011 wedding to Prince William, Kate Middleton wore the royal family's famous Cartier Halo tiara. The piece had been a gift from King George to the Queen Mother in 1936, though at that time the couple was known as the Duke and Duchess of York. Owing to its special place in the family history, many British royals have been lucky enough to wear the piece including Princesses Margaret and Anne.
