How was this bracelet made?

Hi all!! So I have this bracelet that has been around for a LONG time, but I know nothing about it. How was it made? It’s very heavy. And what might be the value? Thanks SO much!!




You see this split shank made two ways. First, it might be cast hard to tell from the image but most likely. Second, the artist takes a piece of wire and cuts it in the middle and separates it.

Thank you so much for weighing in on this piece. It’s so heavy, I thought it might be cast as well. Any ideas on value? Thanks again and have a beautiful Turquoise Tuesday!
