Oval Sapphire and Diamond Halo Pendant in Yellow Gold

This fine jewelry item is a classic halo-style pendant featuring a centrally mounted, oval-cut dark sapphire. The primary gemstone is a deep navy blue, appearing almost black in low light, indicating a highly saturated but likely commercial-grade sapphire. This center stone is secured by multiple prongs and surrounded by a 'sunburst' halo of sixteen smaller round-cut stones, which appear to be either diamonds or white topazes. The metalwork consists of a yellow gold setting with a matching tapered bail at the top. The construction suggests a late 20th-century or early 21st-century manufacturing period, likely between 1980 and 2005, following the popularity of Princess Diana's engagement ring design. There is visible surface grime and skin oil accumulation around the prongs and the facets of the sapphire, which slightly dulls the luster but indicates authentic wear. No obvious large-scale damage or structural repairs are noted, though minor abrasions may exist on the pavilion and crown facets of the sapphire under magnification. The craftsmanship appears to be mid-range commercial quality, consistent with department store or retail jeweler inventory. No maker's marks or gold purity stamps like '14K' or '585' are visible from the upward-facing angle, though they would likely be found on the back of the setting or the side of the bail.
