Multi-Strand Green Marbled Bead Statement Necklace

This is a prominent multi-strand bib-style statement necklace consisting of five graduated strands. The piece is composed of molded beads in varying shapes, including spheres of multiple sizes and elongated marquise or rice-shaped beads. The material appears to be a high-quality vintage plastic, such as Lucite or resin, featuring a deep emerald to jade green marbling with distinct darker swirled inclusions that mimic the appearance of natural malachite or aventurine quartz. The construction utilizes a tiered arrangement where the smallest beads occupy the innermost strand and the largest beads form the outer perimeter, creating a dramatic draped effect. The strands are secured with silver-tone decorative metal end bars and a shepherd's hook clasp with an extender chain, typical of mid-20th-century costume jewelry (circa 1950s-1960s). The beads exhibit a high-gloss finish with no significant surface abrasions, chips, or dulling visible. There is some slight patina on the metal findings, but the structural integrity of the stringing appears sound. The varying translucency within the green marbling suggests a complex manufacturing process characteristic of high-end costume jewelry houses of the era like Trifari or Miriam Haskell, though no specific maker's mark is visible in the image.
