The 1960s and 70s were when French designer Pierre Cardin was at the height of his fashion career—a sartorial iconoclast. Futuristic and geometric forms were his hallmark, with this mid-1970s necklace drawing on both aesthetics. From the gold-toned collar dangles a flower pendant, stylized in shape and reminiscent of the Flower Power movement’s emblems, completed with a contrast silver-hued center.
