The then-Princess Mary of Teck received the Girls of Great Britain and Ireland Tiara in 1893 as a wedding gift. The diamond and pearl tiara had both festoon and fleur-de-lis designs, although the pearls were removed in the mid-1910s and replaced with the diamonds we see today.

Queen Elizabeth II also wore another of her grandmother’s tiaras frequently throughout her reign, the Vladimir Tiara. Imperial jeweller Bolin originally created the tiara for Grand Duchess Vladimir, it features several interlocking diamond circles with removable pearls suspended from the circles.

It was eventually sold following the Russian revolution and Queen Mary was able to buy it for her own collection. She wore the tiara with the pear-shaped pearls, but also had the Cambridge emeralds set in the circles.Â
Queen Mary’s jewellery collection continues to dominate the Royal Family’s vaults event today. On 24 March 1953, Queen Mary passed away at Marlborough House.
