I think it's an ear cuff, like this: https://i.pinimg.com/originals/29/64/2c/29642ca7f7803517fead0e4499e9c5dd.jpg
it actually just hugs the outer conch of the ear, it doesn't require a piercing to keep it on.

im actually so stressed what even is the bartenders piercing its just a floating metal rod in his ear
