Kate Middleton glitters in Princess Diana's diamond tiara

The Duke and Duchess of Cambridge joined the Queen and the royal family at the State Banquet for the King and Queen of the Netherlands on Tuesday night.

Kate was pictured on her way to Buckingham Palace, wearing a blue Alexander McQueen gown and the Cambridge Lover’s Knot tiara, which once belonged to Princess Diana.

The diamond and pearl headpiece dates back to 1914, when Queen Mary commissioned the piece from Garrard. It was passed down to her granddaughter, the Queen, who then gave it to Princess Diana as a wedding present in 1981.

The tiara wasn’t the only piece of jewellery of Diana’s the Duchess of Cambridge wore.

Kate teamed it with Diana’s Collingwood pearl and diamond drop earrings.

They were given to the late Princess of Wales as a wedding present from Collingwood jewellers, and she wore them for numerous balls and engagements.

The Duchess also wore Queen Alexandra’s Wedding Necklace – a new loan to her from the Queen.

According to From Her Majesty’s Jewel Vault, the pearl and diamond necklace is part of Queen Alexandra’s Wedding Parure – a gift from her husband Albert Edward, Prince of Wales (son of Queen Victoria and the future King Edward VII) in 1863.

Kate wore the Royal Family Order for a second time – a personal gift from the Queen. The badge features an image of the Queen and Kate’s one is made of glass, not the traditional ivory.

King Willem-Alexander and Queen Maxima of the Netherlands – who are on a two day state visit to the UK – were also present at the dinner.

Queen Maxima also wowed in the Stuart Tiara for the dinner.

They were welcomed by Her Majesty and the Prince of Wales, and received a Ceremonial Welcome on Horse Guards Parade on Tuesday morning.

During their busy first day, the King and Queen also visited Westminster Abbey to lay a wreath at the Grave of the Unknown Warrior and the Houses of Parliament.

The last State Visit from the Netherlands was by Queen Beatrix and Prince Claus in November 1982.
