The MDI® Diamond Grading Report includes an assessment of the 4Cs – Color, Clarity, Cut, and Carat Weight – along with a plotted diagram of its clarity characteristics and a graphic representation of the diamond’s proportions. For standard round brilliant cut diamonds falling in the D-to-Z color range, the report also includes a MDI® Cut grade.



Our laboratory has the knowledge and instruments needed to thoroughly analyze your jewelry. An MDI® Jewelry Report is an official document in which a jewelry item is authenticated for different purposes, such as insurance, inheritance or purchase. It can also be used to determine the market value of a jewel. These reports provide a general description of the jewel, the diamonds it contains and the precious metals of which it is made.
