Our first tiara out of the Princess Royal's jewelry box (er, vault) makes my list of Most Curious Diadems. We'll call this one the Aquamarine Pineflower tiara.
This piece originally belonged to the Queen Mother. It was an anniversary gift from her husband, King George VI.
Would you put this pine cone wreath on top of your head?
