Princess Kate made a striking return to royal duties at the annual Royal British Legion Festival of Remembrance on Saturday, showcasing a major accessory that had been absent from public view for some time. Dressed in a chic black blazer dress with silver buttons, she adhered to the traditional all-black dress code, complemented by a Royal Air Force pin and a red poppy to mark Remembrance Day.

Kate accessorized the look with a pair of elegant pearl drop earrings and a matching pearl pendant, which added a refined touch to her ensemble. The true highlight, though, was the stunning sapphire engagement ring on her left ring finger — the iconic 12-carat Ceylon sapphire surrounded by 14 diamonds set in white gold, originally owned by Princess Diana. This beloved piece, which Kate had not been seen wearing in public for some time, added an extra layer of sentiment to her sophisticated look.
