We did a lot of shopping at local Jewelry stores before deciding to purchase from National. We liked that we could customize our ring with the color and clarity of our choice, and because we had educated ourselves and had seen several rings with the same color and clarity we ordered, we were confident we would receive the ring of my dreams. WRONG. The diamond was so cloudy I could not believe it. The brilliance was nonexistent. We actually compared the ring with rings that had lower specifications and they had much better clarity and brilliance. The true test was comparing them under a loupe. Obviously there was a mixup somewhere when my stone was selected. I chose National because I wanted a better quality ring than I could get at a mall Jewelry store for less. I didn't get that. However, National stood by their return policy and my refund was issued promptly.
