No end of issues. One of the most important purchases you'll make in your life and they could care less. Ring has lost 11 accent diamonds over the years and customer service is terrible. Have sent it back for repairs twice specifically telling them that the prongs need to be fortified and after both repairs we lost diamonds again after just a few weeks. My wife is very careful with it and almost never wears it now because of all the issues. Customer service is manipulative and tries to strong arm you into cancelling your reviews on the promise of helping but then don't follow through.
