With fewer than three weeks to go to the opening of the 2014 CIBJO Congress in Moscow on May 19, 2014, the sixth of the CIBJO commissions’ Special Reports has been released. Prepared by the CIBJO Gemological Commission, headed by Hanco Zwaan, the report considers how gem labs may act to promote the harmonization of standards and nomenclature.

“In view of concerns that have been raised about inconsistencies in results presented by laboratories, we have explored how laboratories worldwide could work together and harmonize with the trade, to improve consistency, reliability of information and consumer confidence,” writes Mr. Zwaan. “Closer cooperation between the labs is needed to fight disharmony, because inconsistencies occur in both nomenclature and the reporting of results, for instance in the areas of origin and determination of treatments.”

Among the specific items on the agenda of the CIBJO Gemmological Commission’s meeting in Moscow are the use of colour descriptive terms, such as “pigeon blood red,” “royal blue,” and the nomenclature that should be employed to distinguish hydrophane from stable precious opal.
