Victorian/Art Nouveau Style Green Gemstone and Seed Pearl Pendant

This appears to be an antique or vintage pendant, possibly designed to be worn on a necklace or as a chatelaine accessory. The pendant's design is highly ornate and asymmetrical, suggesting a potential Art Nouveau or late Victorian aesthetic, likely from the late 19th or early 20th century. It features a prominent oval-cut green gemstone, possibly a peridot or green glass imitation, centrally set and surrounded by intricate metalwork. The metal appears to be a gold-toned alloy, possibly brass, gold-filled, or a low-carat gold, displaying a significant amount of patina and discoloration consistent with age, appearing somewhat darkened and dull in areas. The design incorporates scrolling foliate motifs, resembling vines or leaves, embellished with numerous small, round, bead-like elements that could be seed pearls or small metal beads. Some of these small beads appear slightly irregular in shape and size. There are also smaller, clear or very light-colored stones, possibly small diamonds, paste, or glass, integrated into the design, though their clarity and setting are difficult to ascertain from the image. The overall construction implies a delicate, handcrafted quality, typical of periods favoring intricate details. There are visible signs of wear, including surface abrasions and potential tarnishing on the metal. The condition of the central green stone seems fair, with some reflections obscuring precise details about its facets and surface. No discernible maker's marks or signatures are visible in the provided images, so the exact manufacturer or origin is unknown without further inspection. The craftsmanship indicates a piece intended for decorative rather than purely functional use, with attention paid to aesthetic balance despite its asymmetry.
