Maxwell stated: “Unlike most of the tiaras worn at British royal weddings, which are usually loaned from the royal collection, this piece was completely new, and was actually a gift from Queen Elizabeth and Prince Philip.”

Because it became her personal property, in “true Fergie style”, the Duchess of York continued to wear the tiara after her wedding and even after her divorce.

In addition to her visits to Australia and Canada, “Fergie also wore the extravagant headpiece to Elton John’s white tie ball in 2001, because…why the heck not?”, said Maxwell.

But despite its grandness, Sarah’s York Tiara was relatively modest in comparison to other brides in the UK Royal Family.
