Vintage Filigree and Butterscotch Bead Long Necklace

This is a vintage long-strand necklace, likely dating from the early-to-mid 20th century. The piece features a rhythmic arrangement of round, opaque beads in a soft butterscotch or custard-yellow hue. While the exact material would require a hot needle or chemical test to confirm, the color and texture are consistent with vintage plastics like Bakelite, Galalith, or Celluloid, or possibly dyed natural stone. Interspersed among the beads are intricate, openwork metal filigree spacers with a quatrefoil floral motif, which appear to be made of a non-precious base metal with a darkened, aged patina or bronzed finish. The necklace incorporates a secondary delicate chain detail near the base, creating a subtle tiered effect. The beads are individually linked with wire loops rather than strung on cord, a common construction method for durable costume jewelry of the Art Deco or Mid-Century periods. Each bead shows slight variations in color and opacity, suggesting a manufactured organic aesthetic. The condition appears to be good for its age, with some visible oxidation and darkening on the metal components, which is characteristic of vintage patina. There are no obvious signs of cracked beads or broken links in the photograph, though the wire loops show slight irregularities consistent with hand-assembly and age.
