GIA Offers Origin Reports for Colored Diamonds

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.”
