Silver filigree bracelet

I 've had this silver filigree bracelet for a while.
Its nice and delicat. The small green stones could be aventurine or chrysophase.
I had one link removed because its a bit to tall for me, and they cleaned it up when they returned it to me. So all the patina has gone.
Does anyone have an idea on how old this bracelet could be?
I think it could either be from the twenties or thirties, but it could be fairly modern too. You can still buy new filigree jewelry these days. But then again, I m no expert.
Thanks for your advice!
