The Mournful Cineraria’s curved handle is pale green with a small, gold section at its base and a flat, black pommel. The shaft of the blade has a “T” shape and each of its ends is a spike resembling those on the Nobody sigil. The main blade is comprised of a thin arc on the underside of the shaft. The arc is lined by four spikes that decrease in size as the lower they are on the weapon. These four spikes are also similar in shape to those on the Nobody symbol. The base of the blade is gold, the shaft is lilac with indigo edges, and the main blade and the spikes on it are white with faint, lilac tips. The Mournful Cineraria bears an odd resemblance in color and in shape to Xigbar's Sharpshooter Arrowguns.
