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.

I have examined the digital representation of this vintage costume jewelry lot. The primary piece is a mid-century revivalist tassel pendant featuring silver-toned base metal and a faux-turquoise resin or glass cabochon. Based on the openwork filigree and the specific double-link chain construction, these pieces are characteristic of mass-produced fashion jewelry from the 1960s and 1970s, likely manufactured by accessible brands such as Sarah Coventry, Monet, or Avon. The condition is categorized as 'fair to good' for estate-found items. I observe visible oxidation and 'pitting' on the silver plating, particularly at the friction points of the links and the tassel cap, which suggests significant wear to the base metal. The faux stones appear intact but lack the natural irregularities of genuine turquoise. In the current secondary market, demand for non-signed, plated costume jewelry remains steady for 'boho-chic' fashion, though it lacks the investment value of sterling silver or high-end designer costume pieces (e.g., Trifari or Dior). Limitations: This appraisal is based solely on visual inspection of images. It is impossible to definitively determine the metal composition (e.g., presence of nickel or silver content) without a professional acid test or XRF scanning. I cannot verify the material of the blue cabochons; while they appear to be resin or glass, physical 'tooth tests' or thermal conductivity testing would be required to rule out stabilized low-grade turquoise. Verification of value would fluctuate based on the discovery of a maker's mark on the clasps, which are not visible in the provided view.
