Faceted Black Spinel or Onyx Beaded Necklace with Silver Bolt Ring Clasp

This item is a contemporary-style necklace featuring a continuous arrangement of small, faceted black beads, likely black spinel or high-grade onyx. The beads are uniform in size, approximately 2mm to 3mm in diameter, and exhibit a high vitreous luster due to their multi-faceted surfaces which catch and reflect light. The necklace is strung on a durable, dark cord or wire, terminating in a silver-toned metal closure system. The hardware consists of a classic spring-action 'bolt ring' or 'spring ring' clasp and a flat, rectangular stamped metal tag (hallmark plate). The overall length appears to be approximately 16 to 18 inches, consistent with a choker or princess length fit. The condition is excellent, showing no visible signs of bead chipping, abrasion, or thread fraying. The metal components show a bright, polished finish with minimal oxidation, suggesting it is a relatively modern piece. The precision of the faceting indicates high-quality lapidary work, often associated with modern minimalist jewelry designs. No specific maker's signature is legible from the distance, but the presence of the tag suggests a professional manufacturing origin.
