The tiara has become one of the Duchess’ favourite items and has a long illustrious history connected to it.
It was created originally for Queen Mary back in 1914 by the House of Garrard from pearls and diamonds owned by her family.
Queen Mary is said to have got the idea for her tiara from the Cambridge Lover’s Knot that belonged to her grandmother, Princess Augusta, Duchess of Cambridge.
The tiara Garrard made for Queen Mary is a copy of the Cambridge tiara, which was eventually sold.
When Mary died in 1953, the tiara was inherited by her granddaughter, Queen Elizabeth II.
Diana famously paired it with a white, pearl-encrusted Catherine Walker ensemble while visiting Hong Kong in 1989.
When she divorced Prince Charles, the tiara was returned to the Queen and reportedly placed in a safe at Buckingham Palace.
After Diana’s death in 1997, the tiara was not seen in public until the Duchess of Cambridge sported it for the Diplomatic Reception at the Palace in 2015.
