This weekend, I told you the story of the Cambridge Lover’s Knot Tiara. Today, we’re going to trace the history of its more famous copy: Queen Mary’s Lover’s Knot Tiara. Here’s a timeline of the tiara that was made iconic by Diana, Princess of Wales…

1913: Queen Mary of the United Kingdom decides it’s time to add to her tiara collection. Rather than buying a completely new piece, she looks to her own jewelry box as a source of materials. She has the Ladies of England Tiara dismantled completely. She also has the upright pearls removed from the Girls of Great Britain and Ireland Tiara, and she has a single pearl taken from the Richmond and Women of Hampshire Brooches. Additional pearls are sourced from various pieces of jewelry that had belonged to her mother, the late Duchess of Teck.

She orders a new tiara from Garrard, which will be made using this cache of gathered diamonds and pearls. For a model, she uses the Cambridge Lover’s Knot Tiara, which was often worn by her aunt and godmother, the Grand Duchess of Mecklenburg-Strelitz. In 1913, the Cambridge Lover’s Knot belongs to Mary’s cousin, Jutta of Montenegro.

The new tiara — Queen Mary’s Lover’s Knot Tiara — features diamond lover’s knot elements framed by pearls. Nineteen pear-shaped pearls are fixed in an upright position at the top of the tiara; nineteen more are suspended from the lover’s knots. The tiara’s frame is made of silver and gold. The piece was made by E. Wolff and Co. on commission from Garrard.

1932: The tiara is altered so that all of the upright pearls can be detached from the tiara. Eventually, the upright pearls are removed from the tiara completely.

1953: Queen Mary dies, and the Lover’s Knot Tiara is bequeathed to her granddaughter, Queen Elizabeth II.

1958: Elizabeth wears the tiara at the premiere of the film Dunkirk; she pairs it on this occasion with Queen Victoria’s Golden Jubilee Necklace and Queen Alexandra’s Wedding Earrings.

1981: Lady Diana Spencer marries Elizabeth II’s eldest son, the Prince of Wales. The Queen presents Diana with several pieces of family jewelry, including the Lover’s Knot Tiara, at the time of the wedding. Many have argued that these were gifts, but the Roberts book confirms that these were basically lifetime loans.
