For sale is this very pretty, 15 1/2" long (measurement does not include tongue on clasp), gilt brass and pierce, molded green glass necklace dating to the Art Deco era. The back of the almost 1" x 5/8" bezel set glass clasp is signed F.N. Co. for the Fishel, Nessler & Co. of New York, NY. The oval links remind me a little of Pac-Man and they measure almost 1/2" wide. They are done in both textured and smooth links and are called "bookchain" simply because of the way they are "folded". No damage, but a few of the links are discolored and a light polishing would help. Necklace weighs 43.9 grams and clasp is "hidden" inside faux coral link.
