Daena Borrowman, Marketing Manager at jewellerybox, explained to Express.co.uk: “The Grand Duchess Vladimir Tiara is rooted in the Russian Revolution.

“It was commissioned from the Romanov court jeweller Bolin by the Duchess Marie or Grand Duchess Vladimir after she became the wife of Grand Duke Vladimir Alexandrovich of Russia, the uncle of the last Romanov emperor, Nicholas II.

“When the Russian royals were forced to flee to safety, her son Grand Duke Boris had someone sneak into the Vladimir Palace disguised as a worker and transport all the royal jewels, including the Grand Duchess Vladimir Tiara, to London, where the Grand Duchess’ son was living in exile.”

The Grand Duchess Vladimir Tiara was later sold to support the Duchess’ children.
