Vintage Necklace-Faux Pearls-Purple Beads-Chain

Interesting necklace with pearl like beads, and faceted purple beads (don't know if those are acrylic or glass). There is a wire twisting around the pearl bead, and the chain has twisted links. The only damage I say was a bit of corrosion on the wire hook. Everything else looks great. My guess is this was from the 1950s.
