I'm getting a newer feel from this piece - if it were over a century old, I'd expect to see more age on the pieces themselves, a bit of patina or dirt but it's looking pretty pristine. Of course, if someone enthusiastically cleaned and polished it, it could look like this - and I agree that the clasp is either a replacement or a sign that it's fairly modern.
In recent times, there has been a lot of similar jewellery made of bronze coming out of India (IIRC).
Great pics by the way! Very clear.
