by kevcenteno » May 23, 2017 After dealing with many vendors for diamonds, I found USA Certed Diamonds on PriceScope. First off, the website has a "vintage" look, which was definitely discouraging. But a few things changed my mind: the diamond listings were constantly updated, the many positive reviews found on PriceScope and other forums, and finally communicating directly with the owner Martin Sheffield. NOTE: Martin is a busy person. I imagine he deals with a lot of inquiries, most of which are probably feelers and not serious buyers. With that said, his response time can be long at first. If you're serious, I recommend following up with him if you haven't gotten a response after a couple of days. Process: After establishing my needs and specifications with Martin, he produced a list of about 2 dozen diamonds that were currently available that feel within my provided guidelines. From that list, we narrowed it down to 4 diamonds, and requested videos and photos of those 4 diamonds. We finally settled on one diamond and sent the purchase order. Before this point, Martin and I communicated by email, but now that we were down to 1 diamond, we were speaking on the phone daily. Martin then sent clear payment instructions to which I followed to the letter. Once payment was received by him, the diamond arrived at his office within 3 days. Since I was local to him, I came over for the big reveal. The diamond was absolutely gorgeous! Martin walked me through the verification steps of the diamond, including weighing, dimension measuring, and checking the all important GIA inscription on the diamond itself. Usually this service would cost you ~$100 at at a jeweler, but Martin has the necessary accreditation and tools to do this for you as a free added service. Overall, I'm absolutely pleased and impressed by Martin's work. Don't let his website fool you, he is the real deal! My only regret was not finding him sooner.
