The De Beers Group of Companies today confirmed that its International Institute of Diamond Grading & Research (IIDGR) has launched its grading service in a number of regions around the world, including Europe, the Middle East, Far East and India.

Following an initial pilot testing of the service in the Far East, IIDGR will now also provide a grading service from each of its laboratories in Belgium, India and the UK.

The service, which employs De Beers’ proprietary grading technology to provide outstanding accuracy and consistency, is suitable for all sizes, colours, shapes and qualities.


However, the service will be available only for natural, untreated diamonds, De Beers said.

Jonathan Kendall, president of IIDGR, said: “Our service aims to provide diamantaires with total peace of mind when it comes to grading. The innovative technology solutions developed in-house at De Beers enable us to provide an extremely accurate and consistent service and our leading capabilities in diamond verification provides customers with an additional layer of confidence.”

Earlier this month it was revealed that 95% of UK customers would like to receive an independent grading report when buying a diamond, yet only 42% actually receive one.

A study by the International Institute of Diamond Grading & Research into attitudes towards diamond grading reports in the UK market revealed a major “gulf” between what customers want and market reality.

The De Beers-owned organisation said the findings bring clarity to the prevalence and demand for grading reports in the UK by exposing the extent to which customers are not receiving the diamond grading reports they desire.
