It might not be ”costume jewelry” either in the sense that it is not made of noble metals, because some old marks could tell who made the piece and also if they were of silver for example.
Well, the first one, is on the back side of vintage handpainted wooden jewelry. The two other could be silver but lacks any silver marks. I have seen this ”swirl” on other vintage jewelry too.
Or anyone who can tell if these are Russian pieces?
