Kate Middleton chose a tiara fit for a queen. Queen Elizabeth II to be precise.

The head of the Windsor clan loaned Kate her Cartier 'halo' tiara for her long walk down the aisle. The dazzling piece of headgear was commissioned in 1936 by the Duke of York (who would later become King George VI) for his wife Elizabeth—the Queen Mum. In 1946, she passed the crown on to her daughter, the current Queen, for her 18th birthday.

If the newly-minted Duchess of Cambridge plays her cards right, she may just get a tiara she can call her own very soon. In 1981, Queen Elizabeth gave Princess Diana the Cambridge Lovers Knot Tiara as a wedding present. Diana returned it following her divorce from Charles. (via Hello!)
