This necklace is probably artist made. No two beads are exactly alike in size as each one was individually made. They are strung on a thick black cord. The largest elongated beads measure 19.5mm X 13mm. The round beads measure 11mm. In between each ceramic bead is a silver spacer bead. They are not sterling but are more like old tribal beads with dents and cracks. The length is 19". Excellent condition with no damage to any of the beads.
