This is one of the strangest pieces I have come across.The necklace has been restrung on coated wire. The beads themselves are all different, all hand carved skulls. I am not sure what the material is , it is not bakelite. They look like they have been buried because they have red earth still in the eyes and crevices. The skulls are interspaced with purple pressed glass beads that have gold detail. The clasp is marked Germany. I don't know if this is original. The beads are about 3/4 inch long by 5/8 inch wide and in nice condition.
