Bracelet Antique Brass or Copper

I bought this about 20 years ago at an estate sale I don’t know how old it is, or what exactly it’s made of. It looks to be brass but I’m not sure. I don’t see any markings of brand or anything at all Decorated with red glass, all are there attached very well 6 hinged pieces of metal, see pictures Only the center hinge on each piece are attached to each other Metal feels heavy, not cheaply made Goth Renaissance costume Make an offer
