Gray & Sons diamonds are not the same as everybody else's. Our GIA diamond rings start with raw diamonds that we send out to our diamond cutter to maximize it’s cut, clarity, polish, proportions, and brilliance. We then send the diamonds to the Gemological Institute of America for authentication purposes and so that every one of our diamond rings can be evaluated for quality.

In addition to their certificate of quality, we ensure peace of mind comes with every GIA diamond ring purchase because we also laser inscribe the unique certificate number, it’s pedigree, on every diamond that we sell. This is to show that our diamonds are indeed one of those diamonds full of mystique and history that can only come from being in the ground for millions of years, and not one of those diamonds born in a laboratory that were made in a week or two.
