The diameter of the wire used in body jewelry, including that used in nasal piercings, is measured using a gauge system. This system uses numbers; a lower number indicates a thicker wire, while a higher number signifies a thinner wire. For example, an 18 gauge wire is thinner than a 14 gauge wire.
Understanding the dimensions of piercing jewelry is crucial for comfort, aesthetics, and the healing process. Selecting the appropriate size ensures the piercing site remains healthy and avoids complications such as migration or rejection. Historically, different cultures have utilized varying thicknesses for adornment, often reflecting social status or tribal affiliation.
