Vintage Silvertone Filigree Blue Crystal Statement Necklace, 20"

I do not know much about this. When trying to research it, there are many. They are listed as anywhere from the 1800-1970s. Some have them listed with a brand name, but I can not find that any are signed. I found no information in any reliable source, so I will only list what I can. What I can say is it is pretty with little wear. It is vintage. It is not signed at all. Please look at the pictures well. Thank you. (BB-F74)24
