This coral colored bead necklace is vintage circa 1920s/30s. They do not test to be bakelite with semichrome but they feel a bit heavier than celluloid to me. They are probably celluloid. They have thier original brass clasp and look to be strung on silk. They should probably be restrung at some point but I prefer to leave them original. They measure 22 inches in length and the beads graduate from about 4mm to 11mm. This necklace is in very good condition. The color is a true pale coral color, not orange or red.
