The most unusual ring hot I have ever seen - double ring, full finger ring, gothic, medieval, romanesque, dungeons and dragons, steampunk

I have never seen such a unique ring in all my life. It is not signed so I'm unsure of the maker or age.

As you can see, it is a full finger ring. It slides right on the finger hot and has two rings to hold it in place.

It's exactly as it looks. See size and measurements in the pics. I wish I knew its history or the history of the maker but unfortunately, I bought it second hand and I don't have any background info on it.

Thanks for looking!
