CIBJO releases Coloured Stone Special Report, looking at technology’s impact and challenge of variety names
With fewer than six weeks to go to the opening of the 2019 CIBJO Congress in Manama, Bahrain, on November 18, 2019, the fifth of the CIBJO commissions’ Special Reports has been released. Prepared by the CIBJO Coloured Stone Commission, headed by Charles Abouchar, the report looks at opportunities provided by new technologies, and also at the vexing issue of gemstone variety names being used for marketing purposes, with few if any agreed to gemmological standards.
