#8: The Queen Mary Fringe Tiara

Worn by: Princess Anne

Owned since: 1919

Estimated value: $5 million*

The Queen Mary Fringe Tiara has such an amazing story behind it that it’s no wonder it was once worth a whopping $5 million! This beautiful diamond piece started as a necklace from Queen Victoria to Queen Mary, who later turned it into a tiara.

Princess Anne has worn this fancy tiara the most, but Queen Elizabeth II rocked it on her wedding day to Prince Philip. Talk about a close call… The tiara almost fell apart on the wedding morning, but the Queen Mother said, “No big deal, we’ve got other tiaras!”
