Heavy old Cuff Bracelet

I think is about 150 years old. am just guessing from the patina and the repairs that you can see on corner or two, think when made and was bent from flat that these resulted.
someone said would be hard to make, is a bronze cuff bracelet with about five figures on it. Believe is bronze,, large crystal structure is visible on the inside that has been smoothed down from wearing. Would be interested in any new information. has one other woman and man,, the man has a shield with a sun on it. My belief is that is is egyptian revival perhaps influenced by a possible craftsmanwoman in Bulgaria. I took it down to a metalsmith jeweler in town and he said this was made by a top level artist as would be very difficult to make. I think is original but would appreciate if anyone has a site for another that is the same, but dont think is out there. Appreciate all comments. You can see from the inside that it has a green patina, from wearing long ago,, has small repair on corner or two. I do like the designs as they are really ornate and the men have great swords and look pretty warlike. With a king or two thrown in and of course beautiful woman with sandles.
