The Difference Between a Diamond Grading Report and an Appraisal

The Difference Between a Diamond Grading Report and an Appraisal

Diamonds are precious stones that many people, especially women, want to own. They use it in jewelries or as part of their collection. When buying loose diamonds on wholesale from either an online or local jeweler, learning the 4Cs isn’t enough. It’s also important to learn the difference between a diamond grading report and an appraisal.

What is a Diamond Grading Report?

The diamond grading report, or certificate, is the official blueprint of a diamond. It describes the shape, measurements, and other characteristics that make it unique. It’s a scientifically based assessment of the diamond’s qualities; including the 4Cs. Diamond experts base it from the International Diamond Grading System that the Gemological Institute of America (GIA) introduced nearly 60 years ago.


A diamond’s value may change over time, but its qualities are unlikely to change. To record these qualities, the GIA developed two additional types of grading reports:

GIA Diamond Dossier – This is the more compact form of the diamond grading report. It’s available for diamonds weighing 0.15 to 1.99 carats. It includes the laser inscription of the diamond’s unique number, which is on the stone’s girdle.

GIA Diamond e-Report – This digital report consists of the graphic representation of the diamond’s qualities. This includes the detailed face up image of the diamond, which was recorded through a grading process.

What is an Appraisal?

An appraisal is the monetary worth of a diamond. It defines the selling price, which is based on current market conditions. There won’t be an appraisal without the help of a grading report, as jewelers need to find out about the diamond’s quality before pricing it. Although the prices change over time, an appraisal gives you an idea about the value of the diamond you’re going buy.

Both of these aspects are important when buying wholesale loose diamonds for sale. Don’t be confused. Just remember that both are different, and an appraisal won’t work without the grading report.
