Diamond Grading Reports

If you've come this far, you are most likely fairly serious about purchasing your next loose diamond or piece of diamond jewelry. Somehow, despite the wealth of information available to the public about diamonds, popular diamond shapes, and the 4 Cs, diamond certification has received less publicity. This is an unfortunate fact, considering that a diamond is only as good as the certified document that stands behind it.

Moving beyond the 4Cs: The 3Ws

  • What

    Commonly known as a diamond certificate, a Diamond Grading Report is an official evaluation of the various distinctive qualities of a diamond. Each diamond contains its own figurative "DNA", which is comprised of the diamond's measurements, clarity, symmetry and a handful of additional characteristics. The Diamond Grading Report manifests as an actual document dedicated to the certification of a single, specific loose diamond. In addition to the aforementioned characteristics, the document typically includes an exclusive Report Number, a Laser Inscription Registry Number, and unique Security Features.

  • Why

    You should absolutely never accept a diamond without a Diamond Grading Report, which serves as a testimony to the quality and authenticity of the diamond you are about to purchase. Don't be shy, this is your investment. If it's not offered to you, ask for it. If it's not provided to you, walk away.

  • Who

    Today's industry leaders in diamond grading reports include the Gemological Institute of America (GIA), the American Gem Society (AGS), the European Gemological Laboratory (EGL), and the International Gemological Institute (IGI). They employ certified gemologists to conduct thorough, consistent laboratory examinations on the diamonds submitted to them for evaluation.
