4. The Durbar Tiara of Delhi

Donn by: Cornwall, Camilla Since 1911, the owner Value Estimate: $2 million Some tiaras are subtle and delicate, while others enter a room 10 minutes ahead of their wearer. You really must not miss the Delhi Durbar Tiara—it is a genuinely stunning item. When Queen Mary had it manufactured for the Delhi Durbar, or the celebration of her formal coronation as Empress of India, in 1911, it made its debut.

For many, this was a genuine endorsement from a mother-in-law to a daughter-in-law. Given its price, it's understandable why. Not many contemporary royals would dare don a tiara quite that large, but Camilla isn't exactly known for her shyness. The Duchess has a history of wearing it with a variety of different diamond accessories, such as necklaces and earrings. The more glossy, the better.
