Vintage Art Deco Celluloid Bead Long Strand Necklace

Long strand necklace with tiny cylinder and faceted mercury glass-style beads. Celluloid pale pink carved beads and larger chartreuse beads (just the colour of undiluted Pernod!). The clasp is copper. I'm not entirely sure the provenance of this piece. I purchased it some years ago as part of a larger collection of pre-1930's jewelry. I am quite sure that the carved and chartreuse beads are older and of a similar era, but perhaps this may have been strung together at a later date. I can't be certain. Either way, it's an absolutely beautiful necklace. 117 cm / 46 inches in length. Vintage. Very good condition. Some variation in the carved beads due to their hand-crafted nature.
