"There is strong interest in this program from miners, manufacturers and retailers. We are adding capacity for evaluating rough diamonds to meet the strong demand."

The GIA scientific matching process starts with the collection of physical measurements and other scientific data from natural rough diamonds. GIA then assigns a unique identification number to each rough stone. When polished diamonds with a rough identification number are submitted for grading services, GIA laboratory staff collect the same data. If the data from the polished gems matches the data from the rough, GIA will confirm the country of origin provided by the mining company and include that information on the Diamond Origin Report.
