Vintage-Style Filigree and Faux-Turquoise Bib Necklace

This is a substantial costume jewelry bib necklace featuring a tripartite frontal design. The centerpiece consists of three graduated, trapezoidal, bezel-set cabochons with a seafoam green to light turquoise hue, exhibiting subtle brownish mottling characteristic of faux turquoise or agate-style resin. Each stone is framed by a decorative beaded metal border. The necklace transitions into ornate silver-tone filigree openwork side panels with floral and scroll motifs. The upper chain sections are composed of a thick, braided wheat-style chain ending in decorative tulip-shaped caps. It features an adjustable extension chain with a lobster claw clasp and a small teardrop-shaped metal charm at the terminus. The metal appears to be a plated base metal with a light antiqued patina, likely dating from the late 20th to early 21st century. The condition appears excellent with no visible tarnishing or missing components; however, the lack of visible hallmarks suggest it is a high-quality fashion boutique piece rather than a fine jewelry item. The craftsmanship is robust, utilizing heavy-gauge links and secure mechanical joins between the articulated segments.
