The nasal septum is the cartilaginous dividing wall between the nostrils. Generally, the cartilage itself is not pierced, but rather the small gap between the cartilage and the bottom of the nose (sometimes called the "sweet spot"), typically at 14ga (1.6 mm) although it is often stretched to a larger gauge (size). This piercing heals within a month and a half to three months also depending on the individual. It should only be stretched by 1mm at a time, and waiting at least a month between stretches is advisable. If a certain point is exceeded, usually about 8mm, the cartilage gets forced towards the top of the nose, which can be uncomfortable.
