Sarah Ferguson, 59, married Prince Andrew, also 59, in 1986.
The pair made their vows at Westminster Abbey, while Sarah wore her stunning ivory duchesse satin dress.
The Duchess of York also wore an incredible diamond tiara on her head, and many wondered where it had come from.
It was revealed the Queen had commissioned the piece herself for the big day.
But Sarah is not the only royal bride to wear a gorgeous diamond tiara, in fact, all royal brides wear a tiara.
Kate Middleton’s wedding tiara was the Cartier Scroll tiara, which later become known as the Cartier Halo tiara. It has 149 baguette-cut diamonds as well as an astounding 739 brilliant cut diamonds of varying weights, with biggest in the middle.
However, the diamonds in this piece are relatively small compared to Meghan Markle’s wedding tiara.
Meghan wore the Queen Mary bandeau tiara, which has large brilliant cut diamonds.
However, these two women were not able to keep their wedding tiaras like Sarah Ferguson did, why is that?
The tiaras Kate and Meghan wore were borrowed from the royal jewellery vault. As such they are not their property, but are the property for the Queen.
However, Sarah Ferguson’s wedding tiara was a personal gift from the Queen.
The piece is named the York tiara, and the Queen gave it as a wedding gift to the wife of her second son. The tiara has delicate scrolls and a large, central diamond on top.
The Duchess of York wore it to the White Tie and Tiara Ball hosted by Elton John at his house in Windsor on 5 July 2001.
Perhaps the Queen did not repeat this gesture after seeing Andrew and Sarah divorce.
Another royal bride was able to keep her royal tiara and that was Princess Diana.
According to reports, it was planned that Lady Diana Spencer would wear a piece from the royal collection, the Cambridge Lover’s Knot tiara. However, the piece was made from platinum and was very heavy.
Therefore Diana wore the Spencer tiara, which belonged to her own family.
Sophie Countess of Wessex, on the other hand, did not own her wedding tiara. She wore a piece created from jewels owned by Queen Victoria.
As such Sophie Wessex’s wedding tiara belongs to the Queen.
