ok... Just for your info, precious metals like silver and gold are stamped for their authenticity. You might have to scan through the jewelery to find one. Silver is stamped .925 and gold 10k, 14k or 18k. It could be gold plated or filled too in which case, it can be stamped as 10k gp and 10k gf respectively. If you can look for these kind of stamps in the earrings, it'll be helpful to know as many of us cant wear non precious metals. Thank you and I hope it helped you...:)
