Cambridge Lover's Knot Tiara
This is another from Queen Mary's collection. The 19 pearl drops came from other pieces of royal jewelry that were given to her as wedding presents, along with brilliant- and rose-cut diamonds. The name comes from the diamond "lover's knot" bows above each pearl. The tiara was inherited by the queen from her grandmother, and she wore it at a film premiere in 1958 before giving it to Princess Diana as a wedding present. Diana wore it many times, and it was returned to the queen after her divorce, but it was dusted off by the Duchess of Cambridge for a diplomatic reception at Buckingham Palace last year.
