Kate, the Princess of Wales, 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 state visit.

Kate Middleton is known to be fan of family heirlooms: she frequently favors one of Princess Diana's favorite tiaras, the Queen Mary Lovers' Knot, and she's also worn jewelry that belonged to the late Queen Elizabeth II. Kate's newest royal accessory, however, was gifted to her by King Charles III.
