From Feb 2010, I'm posting here the flame lily brooches of Queen Elizabeth II (twice) and of Princess Margaret - BUT - I do not have a similar pic of the flame lily brooch for the Queen Mother. I think they are so delicate that the stamens, petals and leaves get moved about.
Joye - do you have a similar pic for the Queen Mother please.
From Feb 2010 - Here we have the Queen's brooch from the Royal Collection, then from a book, and then Princess Margaret's - which I think has a longer stem. I have to conclude that the brooches were all intended to be very close to identical.
