Pia, I posted that (black and white) image for the first time on this board..it was taken from the book on Queen Ingrid. The blog where you found it has copied from this board.
I am posting another picture of Queen Anne Marie of Greece to show you that it is in fact the "Khedive" tiara that is worn by Princess Margaret of sweden in Denmark ....Must have been quite a nice gesture on Queen Ingrid's part to have her mother's favorite jewel to be worn by her (crown princess Margareta of Sweden) granddaughter Princess Margaret on such an important occasion.

The caption says it's : the Khedive - but why would she wear the : Khedive with so many tiaras in the Swedish : vaults? : : : http://atiaraaday.blogspot.dk/2013/12/weekend-bonus-king-edward-vii-ruby-tiara.html#comment-form : : :
