I wear Simply Whispers earrings. They are nickel free which is what I am allergic to. I don't even know they are in my ears, that's how nice they are. I had gotten a pair free & tried them & have ordered several times since over the years. Here's the link if you want to check them out(no I don't work for them,LOL):
