Laboratory-Grown Diamond Reports & Services Details

LABORATORY-GROWN DIAMOND REPORTS

GIA uses the same color and clarity boundaries for laboratory-grown diamond reports as the grading system for natural diamonds, but with fewer quality grade categories. Multiple security features on GIA Laboratory-Grown Diamond Grading Reports ensure their authenticity. For added disclosure and identification, laboratory-grown diamond reports look distinctly different from reports for natural diamonds, the laboratory-grown diamond’s girdle is laser inscribed with the term "Laboratory-Grown" and its GIA report number.
