Every year, the city turns. In autumn, when the trees change in Central Park and the light runs low across the city, the colors of summer give way to something richer. Pomegranate and cherry. Cabernet poured at the end of a long day. Autumn is the season of ripened color, when everything warm has had time to deepen. Red coral and red agate belong to that moment. Black onyx belongs to the evening that follows.
