Cambridge Lovers Knot Tiara: Queen Mary, wife of King George V, commissioned royal jewelers Garrard's to create this tiara in 1913. Its 19 openwork diamond frames each feature a large drop-shaped pearl hanging from a lovers'-knot bow. Queen Mary bequeathed the tiara to her granddaughter Queen Elizabeth, who in turn gave it to Princess Diana as a wedding present in 1981. Following her divorce from Prince Charles in 1996, Diana returned it to the Queen.
