The late Archduchess Rosemary of Austria-Toscana (1904-2001, née Princess of Salm-Salm, and wife of Archduke Hubert-Salvator of Austria-Toscana) was pictured several times wearing an impressive parure of topaz and diamond:
I do not know the origin of this splendid parure (Archduchess Rosemary was born a Princess of Salm-Salm, but she was of Habsburg descent through her mother, while her husband was the grandson of Emperor-King Franz-Joseph). Neither do I know which of her 13 (!) children inherited the parure.
