The Most Stunning Royal Tiaras And Their History

5. The Greville Emerald Kokoshnik Tiara
The Greville Emerald Kokoshnik Tiara originally belonged to Margaret Greville, a fabulously wealthy society hostess and socialite. She was the daughter of a brewery multimillionaire, and had plenty of money to acquire a museum-like jewelry collection. During the time of her death, she was childless and a widow, and so she decided to leave Queen Elizabeth, the Queen Mother, her baubles and gems. 

After the Queen Mother's death in 2002, Queen Elizabeth II inherited the legacy. But the Kokoshnik Tiara was never seen until 2018, when Princess Eugenie wore it on her wedding day.
