For her twentieth birthday in 1946, the then Princess Elizabeth received from her parents a sweetly pretty Cartier brooch made up of two flowers — one picked out in blue sapphires, and the other in pink sapphires and rubies. The princess chose to wear it in the first photo to be released of her and husband Prince Philip with their baby son Prince Charles, and as Queen, she still favours it today. She wore the piece while in Australia during 2011.
