Kate Middleton wears one of Diana's favourite tiaras - the Cambridge lover's knot tiara
The Duchess of Cambridge has worn one of the late Princess of Wales's favourite tiaras to a major diplomatic reception at Buckingham Palace.
Kate was seen wearing the Cambridge lover's knot tiara as she arrived for the function this evening.
It is only the fourth time she has chosen to wear a tiara. The most recent occasion was at her inaugural Buckingham Palace state banquet in October, where she wore the delicate lotus flower tiara.
The dazzling headpiece was a favourite of Diana, Princess of Wales, and was given to her by the Queen as a wedding gift in 1981.
The diamond and pearl-encrusted tiara was made in 1914 and has a strong French influence with a neo-classical design of 19 diamond arches, each cradling an oriental pearl drop.
It was designed by the Queen's grandmother Queen Mary and based on one owned by Mary's grandmother Princess Augusta who married the first Duke of Cambridge.
