#30: Greville Emerald Kokoshnik Tiara

Worn by: Princess Eugenie

Owned since: 1919

Estimated value: $5-10 million*

Tiaras are like the cherry on top for the royal family; you can’t have a royal event without them! The Greville Emerald Kokoshnik Tiara stole the show in 2018 when Princess Eugenie wore it on her wedding day. A mix of shiny diamonds and cool platinum, with a ginormous 93.7-carat emerald right in the middle!

This tiara has quite the story… Dame Margaret Greville originally gave it to the Queen Mother in 1919. Surprisingly, Queen Elizabeth II has never worn it herself, but she’s happy to let her granddaughters borrow this multi-million-dollar dazzler whenever they want. It’s like a family heirloom that adds extra sparkle to special occasions!
