I got my cartilage pierced and i want to by a new earring but i don't know what gauge i should get it in. please help What is the normal gauge for a cartilage piercing?

Its probably 16ga if done with a needle. You can either just call your piercer to be sure or measure it yourself. 16ga is 1.2mm thick and 14ga is 1.6mm thick. If it was done with a gun, its probably 18ga. Which is 1 mm thick.
