What gauge needle to use for 14g belly ring?

Answer 1

You answered your own question. If the jewelry is 14ga, the needle should be 14ga too. I should say though, you don't want to pierce your bellybutton yourself. Its a surface piercing and if you screw it up and it gets infected, you could be left with serious scarring and/or the infection could spread. It would be a better and safer idea to go a professional to get it done
