Black Onyx and Silver Station Necklace with Matching Earrings

This jewelry ensemble features a station-style necklace and a pair of coordinating stud earrings. The necklace consists of a fine, silver-toned cable chain adorned with five polished black stones, likely onyx or high-quality black glass. These stones are arranged in a balanced station layout, with one central horizontal oval bead flanked by two round beads on each side. Each bead is secured by small silver-toned spacers and crimp beads. The coordinating earrings are simple round black cabochon studs that match the color and luster of the neckpiece beads. The stones exhibit a deep, uniform black color with a high-gloss reflective finish. The construction suggests a late 20th-century or contemporary minimalist style, prioritizing clean lines and tonal contrast. From the visual evidence, the metal components appear to be sterling silver or white-toned costume metal; they show slight oxidation or darkening in the crevices of the chain, consistent with age and occasional wear. The overall condition is good, with no visible cracks or deep scratches on the polished surfaces of the stones. The necklace length appears to be approximately 18 to 20 inches, intended to sit near the collarbone on an average bust.

I have conducted a visual examination of the Black Onyx and Silver Station Necklace and matching stud earring set. The stones exhibit a characteristic vitreous luster and uniform saturation consistent with chalcedony-type onyx. The metal components show signs of surface oxidation (tarnish) typical of sterling silver (.925) or silver-plated base metal. The construction utilizes crimp beads and a standard cable chain, which is characteristic of contemporary mass-produced bridge jewelry or artisanal hand-assembled pieces from the late 20th century. The market for minimalist black onyx jewelry is stable but highly saturated. Comparables for similar non-designer sterling silver sets generally sell within the $40 to $90 range in secondary retail environments. The value is driven primarily by the aesthetic appeal and the utility of the set rather than rarity or precious metal weight. The condition appears 'good' with no visible chips to the cabochons, though the chain shows minor kinking potential common in light-gauge station designs. Limitation on Authenticity: This appraisal is based solely on visual evidence. I cannot definitively verify the metal purity or distinguish between genuine natural onyx and high-quality black glass or resin without a physical scratch test, acid testing for silver content, or a thermal conductivity test. To provide a certified valuation, I would require an in-person inspection to locate hallmarks (such as '925') and verify stone density. No provenance documentation was provided, so the value reflects current fair market value for an unbranded set.
