GIA Revises Lab-Grown Diamond Grading System

Article Summary

The Gemological Institute of America (GIA) has announced a significant shift in how it categorizes lab-grown diamonds, moving away from the traditional grading system used for natural diamonds. Instead of assigning specific color and clarity grades, GIA will now classify lab-grown diamonds into two broad categories: premium and standard.

This change reflects the narrow range of color and clarity found in most lab-grown diamonds, with over ninety-five percent falling within a predictable spectrum. GIA executives emphasize that the revised terminology will help consumers better understand the differences between natural and lab-grown diamonds, ensuring informed purchasing decisions.

Industry reactions have been mixed. The Natural Diamond Council supports the move, arguing that lab-grown diamonds should not be marketed as identical to natural stones. Meanwhile, some jewelers believe the shift could create confusion among buyers accustomed to traditional grading reports.

GIA plans to finalize pricing and submission guidelines for the new system by the end of the third quarter, with existing lab-grown diamond reports remaining valid.
