Vintage Gold-Tone Filigree Bolero Slide Necklace

This is a vintage gold-tone fashion accessory designed in the style of a bolero or slide necklace. The piece features a prominent oval-shaped pendant with an intricate openwork filigree design, suggesting a mid-20th-century aesthetic (circa 1960s-1970s). At the center of the filigree work is a small, white cabochon, likely made of milk glass or molded plastic. The pendant is bordered by a twisted rope-style frame that provides a textured finish. The necklace body consists of a long, double-strand rope chain that passes through the slide mechanism, allowing the wearer to adjust the height of the pendant. The ends of the chain are finished with gold-tone spherical beads or finials, which act as weighted balances. The materials appear to be gold-plated base metal, judging by the uniform color and the slight dulling of the finish in recessed areas. The construction suggests consumer-grade costume jewelry popular during the mid-century era, potentially from an American manufacturer like Sarah Coventry or Monet, although no visible hallmark is identifiable from this perspective. The condition is generally good with no visible missing stones, though there appears to be slight surface oxidation and minor scratching on the gold-tone plating consistent with age and occasional wear.
