Are all grading reports created equally?

No. The majority of grading reports, unfortunately, don’t provide enough information about the quality of a diamond. Therefore it’s almost impossible to determine if it’s priced correctly.

There are only a very few diamond-grading reports we recommend. We also recommend the American Gem Society grading report and the newest Gemological Institute of America (GIA) grading report. Why? This new GIA grading report includes a Cut grade; the Cut grade, generally, represents up to 50% of your diamond’s price. Most grading reports lack this score.

GIA Diamond Dossier reports, which are similar to the full GIA diamond-grading reports but designed specifically for diamonds under two carats, don't include a diagram marking all of the stone's unique, microscopic characteristics and flaws. Without this "plot," it would be impossible to determine if the clarity of your diamond poses durability issues.
