Any idea where and when this bracelet is from was made?

This was my mother’s bracelet. It doesn’t seem to be stamped at all. I think she got it maybe around 50 years ago, but I’m not sure. I think it might be silver because it was tarnished, and I cleaned it in silver cleaner which removed most of the tarnish.

I’m not sure what the stone is. It’s possible she got it in Denmark because she bought a lot of this type of jewelry in Scandinavia..

Any ideas? Thanks ????
