GIA to introduce new descriptive grading system for lab-grown diamonds, phasing out traditional 4Cs

Gemological Institute of America will change how it describes lab-grown diamonds. It will use descriptive terms instead of the usual color and clarity grades. This change aims to provide more transparency for consumers. The new system will categorize lab-grown diamonds as 'premium' or 'standard'. This will help buyers understand the differences between natural and lab-grown diamonds.
