Vintage Art Deco Necklace Sterling Silver: Antique, Blue Glass Faceted

I love Art Deco jewelry! This is a stunning, sterling silver, vintage 1910s/1920s necklace. This beauty is done with open back, faceted, blue chicklet shaped glass pieces. There are 13 of them. They are prong set into sterling open back frames. These are all hooked together and sterling silver. Wonderful piece of history@ Measurements: Necklace length 14" long however you can add a chain extender to this easily as it ends with jump rings. Length of glass pieces: 0.30" Weight: 9 grams Condition: Very good vintage condition, vintage patina wear consistent with age. No flea bites to the naked eye. Markings: Clasp is marked Sterling, Necklace marked Pat 3N807 (I think, hard to read it). Tested to sterling silver Please examine enlarged photos for details and condition. Much more beautiful in real life. I am not an expert on vintage jewelry, but I do buy and sell what I love! Since these items are vintage, they may have a wonderful aged patina and are not meant or expected to look brand new. I treasure their imperfections as part of their charm and history.
