Cambria, First of all, thank you for posting a great close-up photo of your bracelet, which allowed me to see that you have a GREAT find. I am not 100% sure, but I think your bracelet has a 'slave trade'
influence. I am 100% sure it is handmade and extremely old. If not, it's a hellava repro.
The majority of slave trade bracelets are bangles with splayed ends. (For an example, look at my banner find.) I don't think yours is an actual slave trade bracelet, but I think it was made with that influence by one of the Tri-Racial tribes/groups whose past generations did make them. Did you find this in Florida? There is a history of Tri-Racials in Florida, which you might want to do some research.
If you will examine your bracelet, you'll see none of the diagonal rings are symmetrical; actually, all are different in size. The larger holes are not symmetrical either. The surface looks to have natural patina from many years of use. It looks to be either brass or bronze.
When I found my slave trade bracelet, I thought it was an old hippy type bracelet, so I threw it in my bag, and didn't realize the age until I got home and cleaned it. I knew it was extremely old; therefore, I had it appraised/professionally identified. If I were you, I'd find a historian who specializes in Tri-Racial groups in Florida and let him/her give you their opinion.
Super neat find
