Septum is the term for a piercing that passes through the nasal septum, which is the cartilaginous wall separating the nostrils. The puncture is usually not made directly through the cartilage itself, but through a thin strip of soft skin underneath it, which is referred to as the “sweet spot.” This placement ensures faster and less painful healing. For this type of piercing, jewelry such as horseshoe rings (open rings with two beads), captive bead rings, or segment rings, also known as clickers, are most commonly used. The advantage of horseshoe-shaped jewelry is the possibility of easily hiding it by simply rotating it inwards into the nostrils, making the piercing temporarily invisible.
