Gauge
What Gauge Is My Piercing Jewelry?
The "gauge" of your piercing is the thickness of the bar that goes through your piercing. In other words, it's the barbell's thickness. Note that the thicker the barbell, the lower the gauge size. So a 12 gauge (or 12G) barbell is much thicker than a 20 gauge (20G) barbell.
