A diamond grading report is the scientific blueprint of a stone’s quality characteristics. A GIA diamond grading report is your assurance that your diamond is a natural diamond, with disclosure of any treatment to enhance color or clarity. The report provides the clear evidence that is vital to a confident purchase. A GIA Diamond Grading Report not only provides expert analysis of Color, Cut, Clarity and Carat Weight, it also contains a plotting diagram that clearly shows a diamond’s inclusions and clarity characteristics. The GIA Diamond Dossier® includes these without the graphical representation of the clarity characteristics. All GIA reports contain security features to prevent them from being forged or duplicated. GIA does not buy or sell diamonds, making an independent diamond grading report from GIA an unbiased assessment of the diamond.
Established in 1931, GIA protects the public through gemological research, education, impartial gem identification and grading services, and instrument development. The world’s foremost authority in gemology, GIA sets the global standard for determining the quality of diamonds and performs research-based identification of colored gems and pearls. GIA created the 4Cs of diamond quality and the International Diamond Grading System™, providing all who buy or sell gemstones with a common language for describing diamond quality. As an independent nonprofit organization, all of GIA’s activities are governed by its mission to serve the public. Visit GIA.edu
