..."The diamond ring is here, and it is FANTASTIC! Thank you so much for your help throughout this process. My wife Amanda said that it is even more spectacular than she had imagined it, and she has VERY high standards. The proportions are perfect, and the stone and setting are wonderful. If you ever need a reference, please feel free to use my contact information; I would recommend you to anybody. Thanks again!"
