#47: Aquamarine Pine Flower Tiara

Worn by: Princess Anne

Owned since: 1940s

Estimated value: $1-2 million*

Back in the 1940s, Cartier whipped up this cool aquamarine pine flower tiara for Queen Elizabeth, also known as the Queen Mother. It was a gift from her hubby, King George VI, but it turns out she wasn’t too keen on it. So, she passed it down to her granddaughter, Princess Anne, for her wedding in 1973.

Princess Anne put her own spin on the tiara, making it shorter and tweaking the aquamarines a bit to match her style. King George VI originally dropped about $1000 on it, but nowadays, it’s valued at a whopping $2 million.
