#32: The York Tiara
Worn by: Sarah Ferguson
Owned since: 1986
Estimated value: $800,000*
When Sarah Ferguson tied the knot with Prince Andrew in 1986, she scored a seriously gracious wedding gift from Queen Elizabeth II. It was a diamond tiara made just for her and Andrew, worth a whopping $800,000!

What’s even cooler? Even after Sarah and Andrew split up, she got to keep the tiara. People thought maybe their daughter, Princess Eugenie, would wear it on her big day, but she went with something else from the royal stash. But hey, at least Sarah’s got something valuable to hold onto, just in case she ever needs it!
