– Queen Mary’s Lover’s Knot tiara is actually a copy of the Cambridge Lover’s Know tiara made in 1933 for Queen Mary.
– Queen Mary gifted the Lover’s Knot to her granddaughter, Queen Elizabeth II, in 1953.
– Queen Elizabeth gave the tiara to Princess Diana as a long-term loan from 1981 – 1996, when she was Princess of Wales. After the divorce and her untimely death, the tiara was returned to the palace.
– The tiara was loved by Diana, but was reportedly so heavy it gave her frequent headaches.
