GIA Diamond Grading Report
includes an assessment of a diamond’s 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. The GIA Diamond Dossier includes these without the graphical representation of the clarity characteristics. The GIA laboratory issues diamond grading reports for loose, natural diamonds in the D-to-Z color range that weigh 0.15 carats or more.
