Def 18g
**EDIT TO 3 STARS**<br /><br />** They tarnish. ** which stinks because they look really pretty but not when they are turning black.<br /><br />These are def 18g not 20g. I didn’t have a problem putting them in cause mine are pierced to 18g but if your only used to 20g you may have a hard time fitting them in. But so far I love these they are beautiful and exactly what I was looking for. My skin is very sensitive so far they are not irritating me. They do say sterling silver so they shouldn’t irritate my nose but if they do I will update my review.
