It’s so pretty and shiny
the back of it that was touching my skin turned blaxk
You decided to 1 star all the products which is pretty unreasonable, you could have just submitted a return within 14 days of receiving it if you didn't like the jewelry. If all the jewelry turned "black" that quickly the issue is most likely you and not the product, sweat or dirt or skin acidity can all cause this. Plenty of other reviews go against these claims, it sounds like gold plated jewelry is not for you.
