Ok. A standard earring gage is different from a nose gauge. Here's how you can tell what gauge it is. Most standard nose rings are an 18 or 20. If you lay a nose ring down on a measuring tape and the diameter of the bar fills the space between the two millimeter marks that is .81 millimeters and is a 20 gauge. If you lay a nose ring on the measuring tape and it fills the space between the millimeter marks and covers both millimeter marks then that is a 1.0 millimeter and is an 18-gauge. :-)
