Just returned a $40k+ diamond that I paid by wire. Never, Never, Never again. This turned out well but could have easily have gone south. USPS only covers up to $25k in insurance. Yeah, they stamped the return box with sides taped and stamped and told me it would be under lock and key literally at all times. But this box could have been opened anytime after leaving my hands, diamond removed and/or switched and then continued to be touched by god knows how many people. Even the store that I delivered this to could have said the diamond was not in the box or it was switched. I know the odds of this happening are very slim but not worth the hassle. I was reviewing a GIA stone that was VS2 and it was NOT eye clean. In fact several jewelers said this was not a typical GIA stone as it appeared to be overgraded and they were amazed it was graded VS2. D color with no florescense but it looked terrible. The GIA number was stamped into the girdle so the diamond matched the certificate. Long story short. Diamond safely returned and another diamond bought at a BM "wholesaler" here in my city. Never will I buy a diamond with a wire (offering no protection) and then buying based on a GIA cert. It was a fancy cut diamond so bought based on the salesperson telling me how beautiful it was when it was not. Pics of the final ring and setting coming. It is a work of art now but took 8 weeks of planning and grief to accomplish my goal.
