Filigree Pendant Necklace with Faux Pearl Accents

This item is a decorative necklace featuring a central spherical pendant suspended from a delicate chain. The chain appears to be constructed from a gold-toned metal, possibly a base metal alloy, and exhibits a somewhat aged or tarnished patina. It is interspersed at regular intervals with small, round, white beads, likely faux pearls, adding a touch of elegance. The pendant itself is spherical or slightly ovoid, crafted with intricate filigree work in the same gold-toned metal as the chain. Its design incorporates swirling patterns and small circular elements, some of which appear to be set with tiny, clear rhinestones or crystals, providing subtle sparkle. A prominent feature of the pendant is a large, dark, oval-shaped cabochon stone, likely a faux sapphire or obsidian, centrally placed within the filigree. The overall construction suggests a costume jewelry piece. There are no immediately visible maker's marks or signatures from the provided image. The style suggests a possible vintage or vintage-inspired aesthetic, perhaps from the mid to late 20th century. The metal shows some signs of wear and slight discoloration consistent with age or frequent handling. The craftsmanship of the filigree is detailed, indicating a reasonably good quality for costume jewelry.
