Flower Brooch with Seed Pearls and Stones

Vintage/Antique Flower Brooch Please see the video as this piece is actually 3 assembled as one- solidly intact but perhaps rotated at some point. The nacre on the top of the pearl has rubbed off, revealing a gritty surfaced nucleus or possibly glass bead. The florets with seed pearls and stones rise from a pollen textured surface. Beautiful! Seeking discovery of the maker from Brooch aficionados... as I do not know. Crown Trifari? Henkel et Grossé? Dior? Flexible to meet up instead of mail if you are in NYC ♡
