What is a GIA Diamond?

GIA Diamond Grading
A GIA Diamond Grading Report is the benchmark for expert diamond grading and the best way to ensure accuracy in your next diamond purchase.
Diamond Treatments
There are several ways that diamonds can be treated to enhance or remove their color and improve their clarity. Every GIA grading report lists the presence of any known diamond treatments.
Diamond Color
The GIA D-to-Z Color Scale is used to evaluate the depth of a diamond’s color. The normal color range goes from D for colorless to Z for light yellow, light brown, or light gray, with variations between receiving a color grade.
How to Buy A Diamond
Regardless of which diamond you choose, every purchase should start with accurate information. A GIA diamond grading report ensures that you know exactly what you are buying.
Simulants, Moissanite and Lab-Grown Diamonds
Purchasing a diamond simulant, moissanite or laboratory-grown diamond can be a great option as long as it is an informed decision. Every GIA report scientifically tests each stone to make sure that it is in fact a diamond.
Diamond Origin
Billions of years ago, 100 miles (161 km) or more in the mantle of the earth, pressure, heat, and carbon atoms converged, creating the first diamonds. Hidden for hundreds of millions of years, volcanic activity transported them to the earth’s surface in magma, forming kimberlite pipes in the process.
