Most belly button piercings are done with a curved barbell preferably made of 14k gold, 18k gold, or high-quality titanium. The standard size for a navel piercing is 14 Gauge (aka 14G). You should never use a barbell thinner than 18G since a higher gauged needle presents more risk of rejection, tearing, and migration.
Also to know is, do belly button piercing holes go away?
If you realize right away that your new notch is not for you, it’s likely to close on its own. “When you get a piercing, it takes four to six weeks for it to heal up, after which time the hole can be permanent,” says New York dermatologist Joshua Zeichner, MD.
