Type: Single-strand beaded necklace Metal: Platinum clasp tag (stamped Pt850); white-metal spring ring and end caps Marks: 26.47 | Pt850 Stones: Black faceted rondelle beads, graduated, with small round black spacer beads at each end (untested) Clasp / Closure: Spring ring clasp with flat stamped tag, rondelle end caps This necklace is a single graduated strand of black faceted rondelle beads. Each disc is cut with a ring of small facets that catch light along its edge, so the strand shows a fine, steely shimmer against its dark ground, and the rondelles sit closer and smaller as they reach the nape. At each end a small round black spacer leads into a polished white-metal rondelle cap. The strand closes with a spring ring and a flat tag stamped Pt850, the fineness mark for 85 percent platinum, with the figure 26.47 struck on the other face. The piece is minimal in line and monochrome in palette, and sits comfortably at the base of the neck.
