Gold-Tone Chain Necklace with Pearl Accents and Ornate Blue Cabochon Pendant

This is a gold-tone chain necklace, characterized by its delicate, likely filigree or cable link construction, interspersed with small, evenly spaced spherical white beads that appear to be imitation pearls. These pearls are located at regular intervals along the length of the chain, contributing to an elegant and decorative aesthetic. The chain culminates in a prominent circular pendant featuring an ornate design. The pendant's base is a textured, gold-tone metal, possibly a cast or stamped component with a rough, organic, or abstract pattern, suggesting a vintage or handcrafted style. At the center of this intricate pendant is a prominent, oval-shaped cabochon stone, which is a deep, rich blue color, resembling a sapphire or lapis lazuli, though its exact material cannot be determined from the image. The cabochon is smooth and polished, contrasting with the textured metal work around it. The overall design implies a decorative piece of costume jewelry, possibly from the mid to late 20th century, given its construction and style elements. The gold-tone appears consistent, suggesting good condition with no obvious signs of significant wear, tarnishing, or damage to the metal or stones visible in the provided image. There are no discernible maker's marks or signatures visible from this perspective.
