What is a GIA Diamond Certificate?

It’s an official diamond grading report issued by GIA (Gemological Institute of America), the world’s leading gemological laboratory. A diamond certificate is to ensure the authenticity and provide an accurate grading of a diamond.

The 4Cs grading was established by the GIA. Color, Clarity, Cut and Carat of diamonds provide a way to compare one diamond to another. A detailed certificate includes full analysis of grading of carat weight, measurement, color, clarity, cut, polish, symmetry, fluorescence and plotted clarity diagram. Each certificate provides a unique GIA report number to represent one particular diamond. With the report number, you can easily view the certificate information from the GIA website report database.
