The result—a dramatic black-and-red design that reinterpreted the runway’s blue-and-black look with added gothic details—was a Catherine Earnshaw-appropriate take on 2026 Haute Couture. And, as if that wasn’t enough, Robbie added an extra-special piece to the ensemble: a heart-shaped Taj Mahal diamond pendant once gifted to Elizabeth Taylor by Richard Burton. As the famous story goes, the emperor commissioned the Taj Mahal (meaning “Chosen One of the Palace”) as a tribute to his love after she passed—a tale that inspired the diamond’s name. The actor then surprised his two-time wife with the necklace for her 40th birthday in 1972.
