New York designer Hanna Sandin of Samma is known for her linked and looped jewelry in brass, bronze, and copper. Her latest collection employs a puzzle-piece effect, like this brass and white bronze Semaphore bracelet. The piecemeal form gives it a geometric, handmade look, and the warm golden tones stand out against darker winter wardrobes. Thanks to the irregular shape, the effect is delicate, but unfussy.

Samma Semaphore bracelet, $127 at Maryam Nassir Zadeh or online.
