Symbols of luck have become de rigueur among local jewelry designers — wishbones, clovers, and horseshoes have all had their moments — but Kora’s Midi Regency necklace is less overt. Though the gleaming brass pendant is modeled after an ancient emblem for luck, the shapely partial ring feels sophisticated, rather than cute. The label’s Africa-made baubles are inspired by ceremonial jewelry and benefit local artisans, so if the symbolism doesn’t work for you, maybe good karma will.
