See the Duchess of Cambridge dazzle in her late mother-in-law's gorgeous tiara.

Kate Middleton has topped off her look with Princess Diana's tiara again! 

The Duchess of Cambridge dazzled at the state banquet for King Willem-Alexander and Queen Maxima of the Netherlands at Buckingham Palace on Tuesday. 

The royal donned a powder blue gown from Alexander McQueen, adorned with the pearl-and-diamond Lover's Knot tiara, teardrop pearl earrings and matching necklace previously worn by the Queen Mother, Queen Elizabeth II's mom, reported by a royal expert. The piece is originally from Queen Alexandra's collection -- a gift from husband King Edward VII in honor of their 1863 wedding, according to From Her Majesty's Jewel Vault

She finished off the regal look with the Royal Family Order, a yellow ribbon and badge of a portrait of the queen.

The Cambridge Lover's Knot tiara was famously worn by Middleton's late mother-in-law. It was originally designed for Queen Mary and was eventually passed down to Queen Elizabeth, who often loaned it to Princess Diana.

Middleton has actually worn the beloved tiara three times before, for the Spanish state visit in 2017, the annual diplomatic reception in 2016 and for the same event in 2015.
