Oh I don't fuss over markings or no markings I just can't wear silver hooks makes my skin close around it and hurts to get them out but gold or rose gold (real or fake) works well
in the cheap earrings like you get at claires or discounted outlet stores you have to make sure they say nickel free on them. otherwise they use nickel to make the cheap ones not sure if it helps you but hopefully.. yes they are gold lol
