Politmore Tiara
The Politmore Tiara was created by Garrard for Florence Bampfylde, though it was auctioned off in 1959. Princess Margaret had the winning bid. You could break the piece into 11 brooches, and it’s worth roughly $1.3 million!

Queen Mary used to wear this beautiful band of diamonds as a choker. However, it was redesigned to become a bracelet that Kate Middleton and Camilla like to wear. This piece has been with the Royal Family since the 1900s and is likely worth around $500,000!
