Art Deco era necklace features rectangles of molded sea green colored glass, foiled and close-backed. This really catches the light, and each rectangle is secured with decorative prongs. The metal is silver -- possibly sterling although there are no markings to indicate silver content. The glass rectangles are set the entire length of the piece for a total of 16 1/2" length. Spring ring clasp is marked Czechoslov. Excellent condition overall, with some mild speckling to foil as is typical for these age pieces. - $200
