Vintage Faux Pearl Necklace with Filigree Box Clasp

This item is a vintage-style pearl necklace featuring a single strand of graduated cream-colored beads. Based on the uniform luster and visible surface characteristics, the beads appear to be synthetic or faux pearls, a popular costume jewelry choice from the mid-20th century. The necklace is secured with an elongated, marquise-shaped filigree box clasp made of a base metal with a tarnished gold-tone finish. The clasp exhibits intricate scrollwork and openwork typical of mass-produced jewelry from the 1950s or 1960s. The construction utilizes knotted thread or cord between individual beads for security and drape, although the metal findings near the clasp show significant oxidation and darkening, indicative of age and exposure to moisture or skin oils. There is visible wear on the metallic platings of the hardware, resulting in a dulling of the original finish. The pearls themselves show a soft sheen, though some may exhibit minor nacre loss or surface scuffs upon closer inspection. The overall craftsmanship suggests a high-quality costume piece rather than fine jewelry, given the lack of precious metal hallmarks and the specific style of the filigree stamping. The piece captures a classic mid-century aesthetic, once standard for formal daywear.

I have virtually examined this single-strand faux pearl necklace. The piece represents a classic example of mid-20th-century costume jewelry, likely dating to the 1950s or 1960s. Upon my inspection of the provided details, the beads demonstrate a synthetic luster characteristic of glass or plastic cores with a simulated nacre coating. The marquise-shaped filigree box clasp is a common finding for this era; the lack of hallmarks and the visible green oxidation (verdigris) on the base metal findings confirm this is costume-grade rather than fine jewelry. The condition is fair to good, with the presence of oxidation and plating wear slightly detracting from the value. Market demand for unsigned vintage costume pearls is steady but high-volume, meaning rarity is low. Comparables sold at estate auctions and vintage boutiques typically fall within the $30 to $70 range depending on the designer (if any) and the integrity of the stringing. Factors impacting value include the visible oxidation near the clasp and potential nacre loss on the beads. Because this assessment is based on images, I cannot definitively determine the bead core material or the presence of microscopic maker's marks. A physical inspection would be required to verify the thread strength and ensure no individual pearls are structuraly compromised. No provenance was provided, which limits the historical value. For a definitive valuation, an in-person test for 'tooth grit' and a chemical test of the metal findings would be necessary to rule out low-karat gold or genuine cultured pearls, though visual indicators strongly suggest simulated materials.
