Offered is a very unusual necklace that I know very little about.  It is made out of decorated black elbow beads alternating with metal skull beads, small sterling spacer beads, a sterling center bead, and finished with a sterling snake S-clasp.  I don't know if the skull beads are sterling or not, but I'm guessing not. It is 22" in length.  Very cool necklace and definitely one of a kind!

As per a kind EBay-er, these are vintage Krobo beads from Ghana, Africa.
