Kate Middleton will wear tiara this week – ‘Hoping for something other than Lover’s Knot!’

“But the Queen might get another new tiara for her this time too.”

Out of the three tiaras Kate has worn in public, one of them is her wedding tiara from 2011, which was the Cartier Halo Tiara, a diadem loved by other royals such as Princess Margaret during her lifetime.

Charlotte White, the head of design at Europe’s largest online diamond jeweller 77 Diamonds, told Express.co.uk the significant royal history behind Kate’s wedding tiara.

She said: “For her wedding in 2011, Kate borrowed the Queen’s Cartier Halo tiara, commissioned by George VI in 1936 for his wife the late Queen Mother, and which was later given to the Queen to mark her 18^th birthday.”
