I have client who sold a 1 carat princess cut to a customer in a v tip head. The customer wore it on honeymoon fell down , got scraped up , and diamond came out of setting. They e mailed my client and asked what to do. She told them to bring it back to her so she could inspect it and reset it. They in turn took it to a major retail chain who reset it into a standard 4 prong setting, AT NO CHARGE. The customer has now brought it back to my client to get sized, the bench jeweler sized it and noticed that the prong was bent. Upon inspection he noticed the fracture from point to culet. The customer is trying to say that this had been done during sizing. Any opinions on this issue?
