Unfortunately, I have no precise information about the whereabouts of this beautiful parure, which was sold at auction in the late 1990s.
I think I had read once that the tiara was in a Middle-Eastern collection, but I do not find again the reference.
I once spotted in Point de vue (Nr. 2957, 23-29 March, 2005) a picture of a lady called Loulou Stoffel (I admit I do not know who she is...) at a party in honour of the American stylist Zac Posen wearing a pair of earrings, whick strikingly looks like the earrings of Queen Marie-Amélie's sapphire and pearl parure:
While googling Loulou Stoffel, I found these two pictures, on which she wears the same earrings (aparently, the pictures were taken one year earlier than the picture above):

I do not know, though, if the earrings worn by Ms Stoffel are from the original parure, or are a mere copy.
