With fewer than seven weeks to go to the opening of the 2015 CIBJO Congress in Salvador, Brazil, on May 4, 2015, the third of the CIBJO commissions’ Special Reports has been released. Prepared by the CIBJO Diamond Commission, headed by Udi Sheintal, the report looks at measures being taken to tackle the infiltration of undisclosed synthetic diamonds into the pipeline, and also the integrity and the diversity of diamond grading systems that used in the industry, the definitions that are used for diamond grading, and the reliability of the graders themselves.

In the report, Mr. Sheintal refers to a recent court case in the United States, at which a consumer alleged that the colour of a diamond sold to him had been “over-graded,” and consequently, he had been charged an exaggerated price.

The scandal has revisited a number of controversial but important questions, Mr. Sheintal wrote. “Is there a single international standard for diamond grading, in which what is stated on a grading report is understood in the same way, irrespective of who issued it? If not, is it not time that we proactively pursue the establishment of an international standard? And who should be grading the graders?”
