There is no thread about Habsburg jewels ... so... did anyone has an idea about some Marie-Valerie' or Gisela' tiaras?? All photographies of the two archduchesses are WITHOUT that sort of jewels... And also Stéphanie: NOT A PICTURE (not one I know) in a court dress with jewels... I saw once a thumb about a misterious MARIE-VALERIE's TIARA but the browser was unable to send me to a picture... the links were closed...
I am NOT specialised in jewels nor the topic interestests me passionately, but the fact seems a little strange... I know austrian jewels disapeared after WW1, but anyway Empresses Elisabeth and Zita were pictured with jewels... why not Gisela, Marie-Valerie and Stéphanie ??. Stephanie assumed so many balls and ceremonies and also Gisela in Baviera and Austria ...
A second answer, related to jewels because weddings days are glittering... : I never saw a picture of the weddings of Gisela, Rudolph, Marie-Valerie. It seems also impossible to see a normal sized picture of the wedding of Franz-Joseph and Elisabeth (and about Elisabeth' sisters weddings and Franz-Joseph' brothers weddings... )

best regards
