The Princess of Wales last wore the sparkling headpiece, a favorite of the late Princess Diana, to the annual Diplomatic Reception at Buckingham Palace in December 2023.

The royal accessorized with earrings from the late Queen Elizabeth’s collection, and donned Queen Mary’s Lover’s Knot tiara ― marking the first time she’s worn a tiara in nearly two years, as pointed out by People magazine.

During an official appearance in Windsor, England, Catherine, Princess of Wales, wore a tiara for the first time since 2023.

The star-studded gala dinner on July 8, held in honor of the first official French state visit in 17 years, saw Macron seated between Princess Kate and King Charles. The 47-year-old politician politely helped to pull out the Princess of Wales' chair and waited for her to sit before taking his own seat beside her.

Princess Kate joined her husband Prince William, King Charles III and Queen Camilla on Tuesday as they kicked off France's state visit to the U.K. The royals gathered at RAF Northolt in Windsor, England, to welcome French President Emmanuel Macron and his wife Brigitte at the start of their three-day state visit.
