A Sterling Silver Halo Pendant Necklace with Black Onyx and Clear Stones

This pendant necklace is crafted from 925 sterling silver, as indicated by its construction and the user-provided context. The piece features a central, round-cut cabochon of deep black onyx, measuring approximately 6-8mm in diameter. The onyx is secured within a decorative halo setting composed of eight small, clear accent stones, likely cubic zirconia or white sapphire, each held by individual silver prongs. The pendant is suspended from a simple, elegant bale attached to a fine-link cable chain of approximately 16 to 18 inches in length. The overall design displays a vintage-inspired or 'Star of David' aesthetic due to the geometric arrangement of the surrounding stones. The metal exhibits a light patina and minor surface micro-scratches consistent with gentle use, particularly on the back of the pendant and the bale. The craftsmanship appears to be of standard commercial quality with secure prongs and a functional chain clasp. The style is contemporary yet timeless, likely dating from the late 20th century to the early 21st century. No specific maker's mark is visible in the provided image, but the 925 silver composition signifies a standard of quality for fine jewelry.
