The 11 Most Stunning Brooches in the Royal Vaults

Dame Margaret Greville has become famous for bequeathing all of her jewelry to the then-Queen Elizabeth upon her passing in 1942. Two diamond ivy leaf clips had been created separately by Cartier — one before 1930 and the other in 1937 — and they were given by King George VI and Queen Elizabeth to their daughter Princess Elizabeth for her 21st birthday. As a princess, she often wore them separately — with one on a lapel and the other on a hat. As queen, she often wears them together.
