LABORATORY-GROWN DIAMOND REPORTS

Hero_SDGR_700x394-01

Synthetic or laboratory-grown diamonds display several features which allow gemologists to distinguish them from natural diamonds. These include visual characteristics such as color zoning, dark metallic inclusions, weak strain patterns and distinctive patterns and colors of ultraviolet fluorescence. Because they represent types of diamonds that are rare in nature, laboratory-grown diamonds also possess additional features that can be detected with gemological instruments.

GIA Laboratory-Grown Diamond Grading Report

The GIA Synthetic Diamond Grading Report provides the same information as the GIA Diamond Grading Report for natural diamonds, using a more general description of color and clarity with the GIA Synthetic Diamond scales.

The GIA Laboratory-Grown Diamond Grading Report provides the same information as the GIA Diamond Grading Report for natural diamonds, using a more general description of color and clarity with the GIA Laboratory-Grown Diamond scales.

The GIA Laboratory-Grown Diamond Grading Report offers the same information as the GIA Diamond Grading Report for natural diamonds, however; a more general description of color and clarity is provided. For added disclosure and identification, the laboratory-grown diamond’s girdle is laser-inscribed with its report number and a statement that the stone is laboratory grown. What’s more, the report itself looks distinctly different from those issued for natural diamonds.

The laboratory issues laboratory-grown diamond grading reports for loose, colorless to near-colorless laboratory-grown diamonds that weigh 0.15 carats or more. GIA Laboratory-Grown Diamond Grading Reports are not issued for simulants, mounted laboratory-grown diamonds or those that have undergone unstable treatments, such as fracture filling or coating. And while laboratory-grown diamond grading reports may be issued for diamonds that have been laser drilled, this stable treatment is prominently disclosed on the report.

GIA Laboratory-Grown Colored Diamond Grading Report

The GIA Synthetic Colored Diamond Grading Report provides the same information as the GIA Colored Diamond Grading report issued for natural diamonds, using a more general description of color and clarity.

The GIA Laboratory-Grown Colored Diamond Grading Report provides the same information as the GIA Colored Diamond Grading report issued for natural diamonds, using a more general description of color and clarity.

GIA Laboratory-Grown Colored Diamond Report

The GIA Synthetic Colored Diamond Report describes a colored synthetic diamond's color grade.

The GIA Laboratory-Grown Colored Diamond Report describes a colored laboratory-grown diamond’s color grade.

The GIA Laboratory-Grown Colored Diamond Report describes the colored diamond color grade of a laboratory-grown diamond. For added disclosure and identification, the laboratory-grown diamond’s girdle is laser inscribed with its report number and a statement that the stone is laboratory grown. What’s more, the report itself looks distinctly different from those issued for natural diamonds.

Both mounted and loose laboratory-grown colored diamonds of any size can be submitted for this report service. The GIA Laboratory-Grown Colored Diamond Report is not issued for simulants, or laboratory-grown diamonds that have undergone unstable treatments, such as fracture-filled or coated diamonds.
