GIA Offers Origin Reports for Colored Diamonds

Organization introduced service for white stones in March.

RAPAPORT... The Gemological Institute of America (GIA) will offer provenance reports for colored diamonds, expanding its existing service matching polished to the original rough.

The organization analyzes the physical measurements and other scientific data from natural rough stones and assigns each a unique identification number. When a polished diamond bearing that same rough ID is submitted for grading, the GIA puts the polished through the same tests the rough went through. If the two results match, the lab will confirm the country of origin for the polished based on information from the mining company that supplied the rough. The GIA launched the report for white diamonds in March as part of its Mine to Market (M2M) program.

“Reaction to the GIA Diamond Origin Report is very positive,” Tom Moses, GIA executive vice president and chief laboratory and research officer, said Friday. “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 new report will include the country of origin for natural colored diamonds, a full 4Cs quality analysis, and a report-number inscription, the GIA noted. Information about the country of origin and diamond formation for each report will be accessible on the GIA’s site.

“There is recognition across the diamond value chain of the potential for building consumer trust with scientifically confirmed diamond origin,” said Anna Martin, GIA senior vice president for global business development and beneficiation. “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.”
