Graduated pearl necklace with clasp

This piece is a classic graduated pearl necklace displaying a uniform creamy to slightly warm off-white coloration across all individual spheres. The necklace features a traditional graduated design, with the largest beads concentrated near the center front and gradually tapering down to smaller diameters as the strand approaches the clasp. Each bead appears to have visible individual knotting along the silk-like stringing material, which is a traditional craftsmanship detail intended to prevent the pearls from rubbing against one another and to hold the strand together if breakage occurs. The necklace is fitted with a decorative, white metal clasp mechanism featuring an openwork, filigree-style marquise-shaped face and a traditional fishhook insert closure. The metal components show standard surface wear consistent with age, but no maker's marks or hallmarks are directly legible from the provided photographic evidence. The overall appearance is consistent with mid-20th-century costume or fine jewelry styling, though the exact material composition of the beads (whether cultured saltwater, freshwater, or simulated/glass) remains unauthenticated due to the limitations of visual inspection alone. The identification relies entirely on the visible physical configuration of the graduated pearls and clasp assembly.

Based on what I can see in the photograph, this item appears to be a classic graduated pearl necklace featuring a traditional tapered layout with individual knotting and a decorative white metal filigree clasp. However, I can't verify from a photo whether the beads are cultured saltwater pearls, freshwater varieties, or simulated glass/plastic materials. A physical inspection would be needed to confirm the exact material composition and the metal content of the clasp. Assuming the piece consists of cultured pearls with precious metal components, comparable vintage graduated pearl necklaces of this style typically trade within the $150 to $300 range in the current secondary market, driven by steady demand for classic mid-century accessories. If physical testing reveals the beads are simulated or the metal is costume-grade base metal, the value would likely drop to the $30-60 range typical of vintage costume jewelry. To fully determine the value and potential origin, this piece would require in-person examination, professional cleaning, and potentially gemological testing to check for nacre thickness and core material.
