The second image of Sienna Miller’s campaign for luxury jeweler Piaget (created to celebrate the Possession collection’s 20th anniversary) was just released and the always-gorgeous actress looks radiant. In a simple blazer and tee, Miller lets the jewels—a 37-diamond and white gold watch and elegant hoop earrings—take centerstage. The campaign’s third and final image will be released later this summer, but for now, you can watch exclusive behind-the-scenes footage of Miller’s shoot here.
