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.
