Natural colored diamonds have been added to the GIA’s Diamond Origin Report Service. The Gemological Institute of America has done this following strong demand for its scientific service, announced in late March. The scientific GIA service matches faceted diamonds, which fall in the institute’s D-to-Z color grading scale, and natural colored diamonds to these stone’s original roughs to confirm their country of origin.

GIA’s executive vice president and chief research and laboratory officer Tom Moses said, “Reaction to the GIA Diamond Origin Report is very positive. 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.”

Experts in the industry say this is one way of the GIA adding global capacity. The scientific matching process begins with the assortment of scientific data including physical measurements from natural raw diamonds. Then, the GIA assigns a UIN (unique identification number) to each rough diamond. When polished gemstones with rough identification numbers are submitted for GIA grading services, the laboratory employees collect the same information. If the information from the polished gems matches the one from the raw stones, the institute will confirm their country of origin, which is provided by the company that mines diamonds, and will include that data on the GIA Diamond Origin Report.

GIA’s senior vice president for global business development and beneficiation, Anna Martin said, “There is recognition across the diamond value chain of the potential for building consumer trust with scientifically confirmed diamond origin. Consumers clearly want to know more about their gems – where they come from, how they are produced and how their purchases contribute to the well-being and sustainability of gem producing communities.”

The Origin Report contains the country where each diamond comes from, the quality analysis of every stone’s cut, clarity, carat, and color, and a grading report number. For an uninitiated, the GIA diamond grading report has an assessment of its four characteristics, collectively known as the 4C’s. The grading report is also known as the “GIA certificate”.

Now, the details about diamond formation and its country of origin are available for each Origin Report in the online Report Check service of the GIA. The service is accessible in its website, through the quick response (QR) code printed upon each report, and in GIA’s “Origin” application. The GIA’s app is available for Android and Apple phones.
