Interesting information Beth!

I do have a picture of Princess Nicholas wearing the Vladimir Fringe Tiara sometime in the 1950s, which is also included in my article on the Vladimir Fringe. While its possible that she borrowed the Tiara back from Princess Elisabeth, I can't think of any other jewels befitting her rank that she still retained (the Rubies were mainly worn by Princess Olga). Possible occasions that Princess Nicholas would have worn a Tiara at in later years include the Pre-Wedding Galas of her grandson Prince Alexander of Yugoslavia in 1955 and the Wedding Ball of her granddaughter Countess Helen zu Toerring-Jettenbach in 1956, though I have never seen pictures of her at those events!
