Kate, 36, was accompanied by 36-year-old Prince William at the sumptuous State Dinner in honor of King Willem-Alexander and Queen Maxima of the Netherlands.

Kate also donned one of the most beloved tiaras of the latest Princess Diana – the tiara of the lover's knot – created by Queen Elizabeth's grandmother, Queen Mary, in 1913, and was a gift given to Diana on her wedding day. The Duchess of Cambridge also wore earrings with Diana's favorite pearls and diamonds, Collingwood, and a beautiful necklace borrowed from Queen Elizabeth's pearl and diamond collection. The necklace, which also features pearls and diamonds, was a gift from King Frederick to Queen Alexandra if Denmark had been passed on to the Queen Mother and figured in the monarch's extensive jewelry collection.
