Vintage Smokey Faceted Squares Choker Necklace with Extender

Vintage smokey choker necklace is about 16" with a 2" extender, so can be worn at longer lengths. Necklace has 19 faceted squares, each measuring about 3/4" x 3/4," and has a silver colored lobster claw closure. Unsure of the material of the squares, but they do catch the light. New, never worn. Very good condition. Measurements are approximate. Smoke free, pet friendly home.
