I came across this photo of King George V and Mary dated 1934 taken during a gala performance. According to the caption their daughter Princess Royal is also present. However, between the King and Queen is Princess Paul of Yugoslavia and on the Queen's left sits Prince Paul. So the lady which is a bit more difficult to identify clearly (the one sitting to the King's right) must be the Princess Royal. Is it at all possible to work out which jewels they are wearing? The only tiara I am able to identify clearly is the one worn by Princess Paul. Is the Queen wearing the Lover's Knot tiara? I am very grateful for any help on this.
