Cabochon Moonstone and Diamond Halo Pendant Necklace

This fine jewelry piece features a round, sky-blue to milky-white cabochon-cut gemstone, likely a moonstone or chalcedony, measuring approximately 6-8mm in diameter. The center stone is bordered by a pave-set diamond halo, which enhances its radiance. The pendant includes a decorative tapered bail also set with small accent diamonds, totaling an estimated 0.15-0.25 carats for the entire piece. The setting and the delicate cable link chain are crafted from 14k or 18k white gold or platinum, based on the bright silver-toned finish. The craftsmanship suggests a contemporary design, likely from the late 20th to early 21st century. The chain appears thin and refined, indicating high-quality jeweler construction. While specific maker's marks are not visible in the provided image, the precision of the stone setting indicates professional quality. Regarding condition, the metal shows a high polish with minimal apparent surface scratches or tarnish. The central cabochon maintains a smooth surface without visible chips or abrasions, and the diamonds appear securely seated in their prongs.
