Vintage Faux Turquoise Costume Jewelry Necklace Lot

This item is a collection of vintage estate costume jewelry pieces, primarily featuring silver-toned metal work and faux turquoise elements. The focal point of the main image is a large, oval-shaped openwork pendant with a filigree or scrolled open-lace design. At the center of this pendant is a cabochon stone in a mottled blue shade, mimicking the appearance of turquoise or matrix-heavy lapis. The metal appears to be a base alloy with a silver-colored plating, exhibiting some surface wear and minor oxidation consistent with vintage costume jewelry. The construction includes a double-link or figure-eight style chain. Attached to one end of the pendant is a substantial chain tassel, a popular design element in mid-20th-century costume jewelry. Additional pieces in the lot include a circular medallion with radiating floral motifs and smaller blue cabochons, as well as several loose chains and components. The style is indicative of the 1960s or 1970s revivalism, often associated with brands like Sarah Coventry or Monet, although no specific maker's mark is clearly visible in the provided photos. The condition appears fair, showing signs of age and typical 'estate' wear, which includes slight tarnishing of the metal finish.
