The listing, VERY UNIQUE NECKLACE has ended.
This Necklace was inherited, so I am not sure how old it is or where it came from.
The black beads are wood, and the rest I believe are brass.
The circular center pieces are what I believe to be brass, copper and some silver tone metal.
It is 28" in length with a hook and eye clasp.
I have not had it looked at to confirm. I just received it.
