Sterling Silver and Black Agate Concentric Circle Pendant/Charm

This item is a circular pendant or charm, likely a component of a necklace or bracelet, featuring two concentric circles. The outer circle is adorned with what appear to be clear or white gemstones, possibly cubic zirconia or white sapphires, set in a continuous line. Each stone is individually prong-set, creating a glittering surface. The inner, smaller circle is similarly set with black gemstones, which, according to the provided context, are black agate. The setting style for both circles appears to be consistent, suggesting a uniform manufacturing approach. The metal throughout the piece has a silvery luster, consistent with the '.925' sterling silver designation provided. While no specific size can be determined without a reference, the intricate setting suggests a delicate to medium scale. The craftsmanship appears to be of good quality, with stones uniformly set. There are no immediately visible signs of significant damage such as missing stones, heavy scratching, or breakage. Some minor surface wear or patina might be present on the metal due to handling and age, though this is not clearly discernible from the image. The contemporary design, with its dual-tone gemstone arrangement, suggests an estimated age from the late 20th century to the present day. The clear/white and black color combination offers a striking contrast, making it a versatile piece. No visible maker's marks or signatures are apparent in the provided image.
