The report is issued for diamonds sizes from 0.08 to 0.998 carats. Block «Technical Information» missing, but there is information about the linear dimensions of the stone. The block «Additional Information» provides for the possibility of placing the company logo. The card includes a container with a diamond, which has protection against opening. On the website of the organization information about the report is confirmed in the form of electronic text with a photo.

The report for a natural color diamond diamond (Natural Diamond Color Grading Report) contains information about the shape of the cut, weight, fluorescence intensity, diamond color, as well as the intensity and color of luminescence in the long wavelength (366 nm) and shortwave (254 nm) ultraviolet radiation and about the presence of laser engraving on the surface of the diamond girdle. In addition, the report provides information on the diamond's color grading system and on checking the origin of the color. As additional options may be included: laser engraving on the girdle surface and packing in a blister-container. The organization’s website is confirmed both as an electronic text and as a document in PDF.

The report for a diamond made of synthetic diamonds (Laboratory Grown Diamond Grading Report) contains information on the main evaluation parameters: the shape and type of cut, weight, color, purity, cut quality characteristics (proportions, polishing, symmetry), fluorescence intensity. Information is also provided on the presence of laser engraving and a block of information on the dimensional parameters of the cut (Technical Information), namely: the linear dimensions of the cut, the proportions of the girdle and its features, the culet, the proportions of the total height, the proportions of the platform, the proportions and angles of the main faces of the crown and pavilion , the proportions of the length of the paired wedges of the crown and the pavilion, the sum of the angles of inclination of the main faces of the crown and the pavilion. Separately, information is given on the evaluation system and the position of the estimated stone parameters on the rating scales, as well as a diagram of the diamond identity (plotting). Laser engraving on the surface of a diamond girdle is included in the mandatory option. As additional options may be included: cut classification by parameter «Hearts and Arrows» and packing in a blister. The organization’s website is confirmed both as an electronic text and as a PDF document..

The report for a diamond from natural diamonds subjected to refinement (Treated Diamond Grading Report) contains information on the main evaluation parameters: the shape and type of faceting, weight, color, clarity, quality characteristics of the faceting (proportion, polishing, symmetry), fluorescence intensity. In addition, information is provided on the presence of laser engraving and a block of information on the dimensional parameters of the cut (Technical Information), namely: the linear dimensions of the cut, the proportions of the girdle and its features, the culet, the proportions of the total height, the proportions of the platform, the proportions and angles of the pavilion, the proportions of the length of the paired wedges of the crown and the pavilion, the sum of the angles of inclination of the main faces of the crown and the pavilion. Separately, information is given on the evaluation system and the position of the estimated stone parameters on the rating scales, as well as a diagram of the diamond identity (plotting). Information about the impact of refining on the estimated parameters is given in the comments on the link, and also indicates the presence of refining signs in a separate text block. If HPHT detection is detected, laser engraving is applied to the girdle of a diamond. As an additional option, packaging in a blister-container can be made. The organization’s website is confirmed both as an electronic text and as a document in PDF.
