Princess Elizabeth celebrated her 21st birthday abroad, touring southern Africa with her parents and sister. This brooch was one of her birthday presents, a gift from 42,000 children in Southern Rhodesia. The schoolchildren were asked to donate a bit of pocket money each to contribute to the creation of this 301 diamond-strong platinum piece in the shape of a flame lily, a national flower.
Returning home from Kenya after her father's death in 1952, this brooch was the sole striking ornamentation on the young queen's black outfit as she descended the steps of her plane - the first glimpse the public had of their new queen. She wears it to this day, recently capturing its sparkle for her 2011 Christmas message:
