The GIA Diamond Origin Report: Diamond Traceability Based on Science



Consumers now, more than ever, have a heightened awareness of sustainably and ethically sourced products. The GIA Diamond Origin Report uses scientific evaluation to provide confirmation of a diamond’s geographic origin. Origin information for a diamond helps you distinguish between natural and laboratory-grown diamonds and deliver a strong message on the good mined diamonds do for the country they come from. Proof of a diamond’s origin provides the peace-of-mind a consumer needs before they purchase and you can use this origin information as a way to build trust and credibility with your customers.

About GIA’s Scientific Matching

As the world leader in gemological research, GIA is uniquely able to leverage over 60 years of scientific research, knowledge and technology to deliver the rough-to-polish matching confirmation for polished stones. GIA will collect data and images for rough analysis. Once GIA receives the polished diamond, GIA uses markers and data identified during the analysis of the rough to scientifically match the polished diamond to its original rough, confirming the diamond’s country of origin and bringing added transparency to the natural diamond supply chain.
