I had already bought the same ring in February 2014 and a stone was gone when my wife retired to wash hands ... Big surprise: there is no warranty on this article. After an exchange of emails with Amazon customer service that I was refused a refund or exchange, I decided to recommend a ring for my wife who has found was very beautiful. And surprise upon delivery ... Luckily this time I have been refunded (because I was within 30 days!)
But ultimately, for a white gold ring, it is expected a much better quality and especially that it is guaranteed especially for quality defects
