  • GIA and IGI are two of many diamond certification laboratories in the world. As each lab uses its own diamond grading system, it is possible that the results of a report issued by one lab may differ significantly from the report issued by another lab for the same diamond.
    In this video, we will be comparing the diamond grading standards of both GIA and IGI by examining the differences between GIA-certified and IGI-certified diamonds of the same Color grade.
