Colored Diamonds

The GIL Colored Diamond Grading Report provides a full quality assessment of a colored diamond including the color grade and color origin (natural or treated, such as HPHT processed or artificially irradiated), carat weight, and clarity along with a plotted diagram of its clarity characteristics. As an optional service, a full color image of the diamond may also be included. For any colored diamond, loose or mounted.

A professional diamond grading laboratory, like GIL, has the ideal conditions necessary to differentiate and grade colored diamonds, and to identify color origin as natural, processed, artificially treated or as synthetic.
