Kate Middleton Has Her Pick of All These Royal Tiaras

Commissioned in 1921 by society favorite The Hon Mrs Greville, and made by Boucheron, the geometric art deco style was typical of its time, and considerably lighter than a lot of older tiaras. It was inherited by her friend the Queen Mother, who had it made taller in 1953 with diamonds from some of her brooches. It became one of her favorites, and after passing to the Queen it has now become treasured by Camilla, Duchess of Cornwall.
