Cool silver & black necklace: I’m almost sure it’s Chico’s (I have many necklaces from there, some posted). But since I don’t see the tiny fob I’m not 100% sure. In any case the metal discs on the black tri-thread look very modern and cool. Needs a cleaning. Please see all discs—one has a “mark” but I think it’s the metal. About 18” as shown.
