HIGHLY REGARDED BRAND IN THE INDUSTRY
Diamond "Certification" or Grading Labs
The price you pay for a diamond largely depends on how the diamond is graded in a grading report and/or "certificate.”
Grading reports by the Gemological Institute of America (GIA), HRD Labs, American Gem Society (AGS), and Gem Certification and Assurance Lab (GCAL) command the highest premium in the diamond industry. However, among the other labs, there are significant discrepancies in how they grade diamonds and assess the 4Cs.
