CUT Grade proportion diamond.

A diamond grading report is a document that is issued by a gemological laboratory after evaluating the characteristics of a diamond. It is used to provide an objective record of the quality of a diamond. The report includes information on the 4 C's of diamond characteristics: carat weight, color, clarity, and cut. It also includes measurements of the diamond's proportions, polish, and symmetry. The report is used by jewelry professionals to accurately assess the quality of a diamond and to determine its value.

As a result of the development of the Scanox device by OGI Systems, all the measures of the diamond's proportion, including its symmetry, can be displayed after a few seconds. This saves a lot of money and improves the quality of the cutting process
