Necklace with green cabochon pendant in a vintage-style setting

This appears to be a necklace consisting of a fine link chain and a decorative pendant featuring a translucent green cabochon stone. The pendant is consistent with designs often associated with Art Deco or mid-20th-century costume jewelry, though a physical inspection is required to determine if it is a later reproduction. The central stone appears to be an oval-cut green material—possibly glass, jadeite, or chrysoprase—housed in a silver-toned metal mounting with leafy or scroll-style decorative filigree work. A small metal tag near the clasp bears a stamped marking that appears to read '1928', which is stylistically consistent with the logo used by the 1928 Jewelry Company. This marking suggests the piece is likely a costume jewelry item designed to mimic early 20th-century aesthetics. The metal shows a slight patina, and the chain is a simple cable or curb link. While the '1928' stamp is visible, it remains an unverified hallmark without physical testing of the metal content and manufacturing methods. Overall, the piece presents as a well-maintained example of vintage-inspired decorative jewelry.

I have examined the digital image of this necklace, which features a green cabochon pendant in a vintage-style setting. Based on what I can see, the piece bears a small metal tag near the clasp with a marking consistent with the logo of the 1928 Jewelry Company. I am treating the attribution to this brand as a working hypothesis, as I cannot verify the legitimacy of hallmarks or metal composition from a photo alone. The central stone exhibits the translucency and color typical of glass or chrysoprase-style materials used in costume jewelry. The metal setting shows scroll-style filigree work with a dark patina that appears intentionally applied to mimic age. The value estimate of $25.00 to $65.00 reflects the typical secondary market range for decorative costume pieces of this style and assumed brand in well-maintained condition. I cannot verify from a photo if the metal is a base alloy or a precious metal, nor can I confirm the exact composition of the stone. This estimate assumes the '1928' mark is an accurate attribution; should the piece be a later unbranded reproduction or an imitation of that specific firm's work, the value would likely sit at the lower end of the spectrum ($10.00-$20.00). Market demand for mid-century style costume jewelry remains stable for wearable decorative purposes rather than high-end investment. An in-person examination by a specialist, testing for metal purity, and verification of the manufacturer's mark would be required to provide a more conclusive assessment of its origin and quality.
