“The GIA Diamond Origin Report uses the Institute’s decades of research and scientifically matches a polished diamond to its original rough, confirming the country of origin information provided by the miner. Accurate diamond identification also remains of continued importance for the trade as well as consumers. GIA has been at the forefront of this through development of screening and identification services and instruments such as the Melee Analysis Service and the GIA iD100® gem testing device.”How does AI work in grading and what improvements will it bring in?
We’re really excited about the future of diamond grading at GIA. GIA has joined forces with IBM Research – combining human expertise with the machine precision of artificial intelligence (AI) – to develop the GIA AI Clarity System. The GIA AI clarity system is built on the standards of GIA’s universally recognised International Diamond Grading System™. The AI is fuelled by data from tens of millions of diamonds examined by GIA’s expert diamond graders in the Institute’s state-of-theart grading laboratories around the world. IBM’s AI technology, combined with GIA’s expertise, extensive data and gemmological-research capabilities, enables us to deliver advancements in consistency, accuracy and speed unlike any other organisation. The proprietary system, now in limited use in GIA’s New York and Carlsbad laboratories, will dramatically expand the reach of GIA’s independent diamond grading reports. Initially concentrating on the most popular diamond sizes, GIA will scale the AI system to bring accurate and efficient diamond grading to more diamond sizes, shapes and qualities. There are also plans to expand the collaboration between GIA and IBM for future projects combining gemmological evaluation and AI.

Where do you see Indian diamond industry five years from now? There are and will continue to exist several key trends in the diamond industry. The one I believe has gained prominence is provenance.Consumers now, more than ever, have a heightened awareness of sustainably and ethically sourced products. The GIA Diamond Origin Report uses the Institute’s decades of research and scientifically matches a polished diamond to its original rough, confirming the country of origin information provided by the miner.
Accurate diamond identification also remains of continued importance for the trade as well as consumers. GIA has been at the forefront of this through development of screening and identification services and instruments such as the Melee Analysis Service and the GIA iD100® gem testing device. In addition, GIA helps spread awareness among consumers about the importance of third-party grading reports and also offering a wide range of gemmological education programmes and courses for jewellers I also strongly believe that the next few years will be key for the widespread adoption of digital initiatives such as AI and blockchain. GIA is already committed to these as a part of the Institute’s digital transformation efforts. The collaboration between GIA and IBM Research to develop an advanced AI system designed to revolutionise diamond clarity grading is a step in that direction. In 2018, GIA collaborated with Chow Tai Fook to deliver secure digital diamond grading reports to consumers for the first time using blockchain technology – developed with leading blockchain solutions provider Everledger and secured by the IBM Blockchain Platform. GIA continues its collaboration with Everledger and JD.com, China’s largest online and offline retailer, to provide customers with independently verified GIA diamond reports and origin information through theJD.com app, as well as on JD.com’s mobile and desktop websites. Everything GIA does – our research, education and of course grading millions of diamondseach year in our laboratories around the world – has the singular mission of protecting consumers
