Parure in cornu/horn from the thirties

Believe it or not, but I bought this parure as a set at a flea market. But it was not in this form when I bought it! The necklace consisted of just some loose beads in a bag, the bracelet was in desperate need of a new string...only the earclips where ok. So I think I payed 2€ for the set. A real bargain.
I did some oneline research for similar necklaces, et voila, a whole new parure!
It dates from the thirties, its made from cornu= horn, I m not sure where it was made or what type of animal the horn is from....so if you can help me fill in the blanks, I would really appreciate it!
I must say I haven t worn it since, so thats a bit of a shame...might put it on more now ;-)
