Hi, I have read here that people's experience is that the stones fall out from the earrings. i just ordered the necklace and it came today It is really cute! However, if the stones are just going to fall out I do not want to pay that kind of money for it...esp since when I inspected it one stone already looked a little off what are your experiences with the durability of the necklace? Also if I do end up returning it..how good is Chanel with returns? Thanks!!
