Vintage Emerald-Tone and Clear Rhinestone Festoon Necklace

This is a vintage mid-century costume jewelry necklace featuring a classic festoon design. The piece is constructed with a silver-tone metal base, likely rhodium-plated brass or pot metal, and is set with a combination of clear and emerald-green glass rhinestones. The chain consists of a double row of small, round-cut clear crystals in box settings, which transition into a more ornate focal point. The center drop is anchored by a large, pear-cut (teardrop) emerald-green glass stone, surrounded by a halo of smaller clear rhinestones. Flanking the center stone are marquise-cut and round-cut green stones, creating a graduated, winged effect. The stones are prong-set, a sign of higher-quality costume jewelry compared to glued-in 'paste' stones. Stylistically, it reflects the glamour of the 1950s or early 1960s, reminiscent of high-end brands like Weiss, Eisenberg, or Trifari. The condition appears fair to good; there is visible tarnishing and darkening on the silver-tone finish on the upper right strand, and some 'dead' or yellowing clear stones are present, indicating moisture exposure or foil degradation over time. No visible maker's marks are discernible from the front, though a clasp or stamp on the reverse would be typical for this period.

I have examined the digital images of this vintage mid-century festoon necklace. The piece exhibits the classic design vocabulary of the 1950s, utilizing high-quality prong settings and a sophisticated mix of pear, marquise, and round-cut glass stones. While the unbranded nature and lack of distinctive hardware suggest a more accessible manufacturer than high-tier houses like Eisenberg, the construction remains superior to entry-level 'glued' costume jewelry. My evaluation indicates fair to good condition. Significant value detractors include the visible tarnish on the rhodium plating and the 'dead' or yellowing clear rhinestones, which suggests foil degradation and possible moisture ingress. This type of damage is difficult and costly to restore, often limiting the piece to the 'as-is' collector market. This appraisal is based on current auction realizations for unsigned mid-century bridal and evening-wear costume jewelry. While the emerald-tone stones remain vibrant—a desirable color in the current vintage market—the condition issues and lack of a signature cap the high-end potential. Please note: This is a visual assessment only. A full authentication would require physical inspection to verify metal composition, check for hidden maker marks on the clasp or reverse, and assess if the darkened stones have compromised the structural integrity of the settings. The absence of provenance documentation further limits the ability to assign a higher value based on historical significance.
