Gold-tone herringbone chain necklace with pendant

This piece consists of a flexible herringbone-style flat chain necklace featuring a central V-shaped or chevron-like rigid metal element that drops down to support a single, round faceted solitaire stone in a prong setting. The metal has a polished yellow gold-tone finish, reflecting light brightly across the textured or woven links of the chain. The stone appears clear and brilliant-cut, suspended at the focal point of the drop. There are no visible hallmarks, maker's marks, or stamps discernible in the provided image. The overall condition appears generally good and clean, displaying minimal surface wear or tarnishing in the photograph. Stylistically, the design is reminiscent of mid-to-late 20th-century fashion jewelry, though any specific period or material composition remains unverified without physical testing or optical magnification of potential stamps.

Based on what I can see in the photograph, this jewelry piece features a gold-tone herringbone chain and a central pendant with a round faceted solitaire stone. I cannot verify the material composition, metal purity, or stone type from a photo alone; physical testing and optical magnification would be needed to confirm whether the metal is plated base metal or precious gold, and whether the stone is glass, synthetic, or diamond. There are no visible hallmarks or maker's marks discernible in the image. Assuming this is a mid-to-late 20th-century fashion jewelry piece of typical construction, comparable items in generally good and clean condition typically trade within the $50 to $150 range in the secondary market, driven largely by decorative appeal rather than intrinsic precious material value. If the attribution or assumed vintage style is incorrect, or if the item proves to be a modern reproduction or unbranded fashion piece, the value would likely decrease to the $25-$50 range. To establish a more precise evaluation and authenticate the materials, an in-person physical examination, hallmark verification, and professional gemological testing would be required.
