I had a bad experience with the gold earrings as they turned green after sweating in the earrings often when I worked out so the team was so nice to send me sterling silver to try when working out. These do not turn at all! I think it was my skin and hormones that made the gold turn so I don’t think it would do that for everyone. So thankful for the team helping me out! I wish I did sterling silver from the beginning, they’re perfect!!!
