New GIA Diamond Grading Report and GIA Diamond Dossier®
On January 1, 2006, the GIA Laboratory introduced new versions of the GIA Diamond Grading Report and Diamond Dossier®. These new reports now provide a single, comprehensive cut grade for all standard round brilliant diamonds falling in the GIA D-to-Z color scale and Flawless-to-I3 clarity scale. Diamonds receive one of five cut grades from Excellent to Poor.
New reports also contain expanded proportion data provided within a graphic representation of the diamond. The new diagram provides all the proportions used to determine the GIA cut grade.
New reports contain descriptions of the 4Cs and can be used to assure consumers they are purchasing a diamond that has been thoroughly measured and graded for Carat weight, Color, Clarity and Cut by the world's foremost authority in gemology. The procedures established by GIA also determine the nature of each diamond. The Institute discloses any evidence of treatment detected during the grading process on the diamond grading report.
Updating Existing GIA Diamond Grading Reports
The GIA Laboratory has collected the necessary proportion information on most of the round brilliant diamonds it has graded since January 1, 2005, so it will not be necessary for most clients to send diamonds back to receive a new report with the cut grade. If you already own a diamond with a GIA Diamond Grading Report or Diamond Dossier®, and would like to exchange your original report for a new version, here are some guidelines. Please note that in all cases your original report must be returned to the Laboratory before a new version is issued.
Reports will be reissued or updated upon request following these parameters:
If your report is dated between January 1, 2005 and December 31, 2005: simply return your original report to the Laboratory, and a new report containing a cut grade will be issued to you. In a small number of cases, you also may need to submit your diamond to the Laboratory. To find out whether your diamond must be returned, please go to GIA Report Check and enter your diamond’s report number and carat weight. If Report Check returns a cut grade for your diamond, the diamond does not need to be submitted and a new report will be reissued to you upon request for a nominal fee.
If your report is dated prior to January 1, 2005, or if Report Check DOES NOT return a cut grade for your diamond: your diamond must be submitted to the Laboratory for an Update service so that additional measurements may be captured before a new report with a cut grade will be issued. The new report will reflect the current date, not the date of the original report. Standard update fees will apply.
