To celebrate, Karl Lagerfeld photographed friends and Chanel ambassadors – including Kristen Stewart, Lily-Rose Depp, Keira Knightley, Vanessa Paradis and Julianne Moore – wearing the pieces for a series of portraits. Shot in the famed Paris apartment of Mademoiselle Chanel, each star also wore a Chanel Haute Couture look designed to complement each piece of jewellery.
