In 1936, the Duke of York (later King George VI) bought this tiara for Queen Elizabeth II’s mother, the Queen Mum. Cartier called it the “Halo” tiara. A fashion journalist also dubbed it the “Scroll” tiara. Both names stuck.

Wedding costume tradition dictates “something old, something new, something borrowed, something blue.” As her mother gifted the tiara to Queen Elizabeth II on her 18th birthday, so the Queen loaned it to Kate on her wedding day.

That Princess Catherine, Duchess of Cambridge, wore a priceless antique is thrilling. That she also has Diana’s engagement ring puts her at the pinnacle of provenance. She looked radiant.
