I bought these for my for my 3 year old after she lost a pair of solid 14kt gold pearl earrings and and diamond studs with solid gold stem. Was worried with these being plated metal they would irritate her ears. Happy to say they have not. She has been wearing them for more than 6 months now. They have not tarnished, lost sparkle or the backing come loose. She bathes in them, swims and sleeps in them no problem. Am now planning to get a pair for myself..chuckles
Also, the stones are not too glassy.
