Mr Hinds added: “Sarah Ferguson debuted the York Tiara to the world following her wedding ceremony, a move seen to symbolise her new status as a Princess.
“But not just a wedding accessory, the Duchess of York continued to wear the tiara through her time in the Royal Family – and it even made appearances after her divorce from Prince Andrew in 1996.
“The York Tiara’s final public appearance was in 2001, and the piece has not been publicly seen since.
“It’s typical that a royal bride borrows a piece from the Queen’s personal collection, but the York Tiara was a break from custom, with the Duchess keeping it beyond the wedding ceremony.
