In 2023 the Gemological Institute of America grading laboratory will offer less expensive, more stripped-down lab-grown diamond reports which will list the 4 Cs but leave out other information specific to lab-grown diamonds. Reflecting how the market has evolved and the fact that there is less consumer or retailer interest in growth method and treatments, the new report will not specify growth method or post-growth treatments. As this information is costly to determine, the new report will have a lower cost.
