Plastic beads that were molded to simulate carving were very popular in the Art Deco era. What sets this 1930s necklace apart is the colors — dark blue on cream. This combination and the design are lovely, and the different shapes of the beads add interest. Even the screw-in clasp forms a bead. I’m not sure what type of early plastic this piece is (possibly Galalith, the French equivalent of Bakelite) – it’s light, wonderful and fun to wear in any case.
