Some architect design their own homes, others their own furniture, and some, their own jewelry. Portuguese firm 38n9w Arquitectos designed a one-piece necklace out of resin. Called "Lace," it looks reminiscent of both the firm's arngular architecture and human biology—inspired by a bone, or veins? Good for a dramatic look. Brazilian architect Oscar Niemeyer also designed a line of jewelry, including sinuous gold bracelet after his own curvy architecture. •
