These are super comfy and look great on. I wear them in my 2nd piercings. However, the posts have turned black. So I'm not sure if these are truly sterling silver. I cleaned them, so it's not just tarnished. It's a mystery metal. I have sensitive skin, so I don't keep them in for very long anymore. But I've never had a reaction. Nobody can see where it's black because that part is in my ear. The hoops have stayed silver in color.
