Vintage Tribal Look Carved Chunky Bead Necklace

Vintage tribal style necklace with carved looking beads.The beads have an ivory and wood look.Some are hollow on the inside.The hollow beads appear carved when looked at through a magnifier, but I can't say for sure.The beads are of some type of plastic, but are not bakelite.The center block bead looks like a basket weave.The design is on all four sides of the bead. In between carved looking beads are reddish-brown round beads and brass colored spacers. About 20" with toggle clasp.
