This is an earthy chunky necklace circa 1975 is 26" long of ivory colored, black and red carved and dyed beads with brass bead spacers strung on string.  Three large ridged brass beads give weight and allow the four strands of smaller colored beads to hang nicely in front.  The rest of the beads, also made of bone, are round disk shapes and alternate in colors all the way to the barrel clasp in back.  This is a spectacular and colorful African look.
