I made sure to test out these earrings for at least 2 weeks before leaving a review. I got these for my infant daughter in the smallest size, they still look a little big on her. 12mm is like a dime size. I was doubting the gold bc of the other reviews but the hoops have not tarnished, they’re real gold and don’t irritate my daughter’s skin. You can’t find real gold anywhere else at this price.
