Kate Middleton rocked late Princess Diana's dazzling favorite diamond Tiara as she arrived with Prince William at the Queen's annual Diplomatic Reception in a chauffeur-driven Bentley.

The tiara was originally made by Queen Mary in 1914 to her own design from pearls and diamonds.In her will Queen Mary left the tiara to to the Queen who wore it frequently, including at an evening event in 1955.

In 1981 she gave it as a wedding present to Prince William's mother, Diana, who wore it for the first time at the state opening of parliament that November.

Buckingham Palace was unable to confirm last night whether the tiara had reverted to the Queen on Diana's death and had now been given to Kate, or whether it was just on loan for the night.
