AJC Textured Gold Tone Link Necklace with Imitation Grey Pearl is a great dimensional modernist piece. The American Jewelry Chain Co. was in business from the 1920s to the 1990s. This piece appears to be from the late 70s or 80s. The waffle like textured links splay out to give the piece shape. It measures approximately 19 1/4 inches with a fold over lock clasp back closure. The pyramid like center piece raises up, and has a faux grey baroque pearl. The center width is 2 5/8 inches. Signed on the back of the pyramid in a cartouche, AJC.
