Vintage Gold Tone Pendant Necklace and Matching Earrings Set

This jewelry set comprises a pendant necklace and a pair of matching clip-on or screw-back earrings, all featuring a gold-toned metal and a central dark stone. The pendant is a circular, swirling design with four prominent curved arms, each adorned with open filigree-like work, emanating from a central bezel-set oval or round dark stone, possibly onyx or dark glass, though further testing would be needed to confirm. The metal appears to be a gold-tone alloy, exhibiting a warm yellow hue that suggests either gold plating, gold-filled material, or a base metal alloy. The accompanying necklace features a delicate Rolo or belcher chain. The matching earrings mimic the primary swirling motif of the pendant, with each earring having a single dark central stone surrounded by similar filigree arms. The findings on the earrings, though not perfectly clear, appear to be of a non-piercing type, possibly clip-on or screw-back mechanisms given their visible structure. The overall condition appears good for a vintage set, with some potential minor wear consistent with age, such as slight surface scratches or the beginnings of patination on the metal, though these are not distinctly visible given the image quality. The intricate scrollwork and design suggest a mid-20th-century aesthetic, possibly from the Art Deco revival period or later vintage. The craftsmanship, particularly the filigree-style details, indicates a moderate level of quality for costume jewelry of that era. There are no discernible maker's marks or signatures visible in the provided images.
