Vintage Strand of Pearls w/ Sterling Silver Clasp

NPC51. String or strand of pearls, esti 15“ long NOT including the clasp/closure. Believe this is vintage. The ornate clasp is marked STERLING on the inside, between the two pretty sides. ASSUMING these are FAUX, because they are just too perfectly sized & symmetrical. They are on a thin string. There is nothing between the pearls that I could see, meaning not knotted. I just don’t know. Shorter, Choker size. Absolutely gorgeous. Feminine. Graduated. 🥰🌸
