World Jewellery Confederation welcomes new ISO diamond grading standard
The World Jewellery Confederation (Cibjo) has welcomed the new publication by nongovernmental body International Standards Organisation (ISO) of the internationally recognised diamond grading standard and says it is a historic moment for the global diamond industry.
The confederation explains that the standard is the first-ever that has been approved by the body that specifies the terminology, classification and the methods to be used for the grading and description of single unmounted polished diamonds.
