Gemma Couture makes the kind of fine jewelry that slips beautifully into everyday life. Founded by twins Yonatan and Yael Livian, the collection draws on decades of family expertise in gemstones, pairing diamonds and rich color with a fresh, wearable sensibility. Their flexible and stretch designs are particularly clever - bringing ease to pieces that still feel beautifully polished. These are lovely foundations for a jewelry wardrobe, whether worn alone or layered with pieces you've collected over the years. K.J.
