The GIA will also make more information available on each polished stone on its online Report Check service. The new service will be available only if the original rough diamonds are submitted together with the resulting polished diamonds, “so that they can be matched to each other and to confirm the origin information provided by the participating mining company”. GIA President and CEO Susan Jacques commented: “In recent years, there has been a growing demand for transparency and traceability in the diamond industry. Consumers want to know the origin of products and their socio-economic and environmental impact […]”.

According to the report, the GIA has already processed “thousands of rough diamonds ranging from 0.15 carats up to more than 100 carats for the service”. The GIA added that “a growing number of miners, manufacturers and retailers are participating in the Diamond Origin Report program, including Alrosa”.
