With fewer than four weeks to go to the opening of the 2018 CIBJO Congress in Bogot\u00e1, Colombia, on October 15, 2018, the sixth of the CIBJO commissions\u2019 Special Reports has been released. Prepared by the CIBJO Gemmological Commission, headed by Hanco Zwaan, it reveals the results of a survey of 23 gemmological laboratories from around the world, about whether and how they report on synthetic and treated diamonds.<\/p>\n

\u201cThe survey provided a clear picture of the similarities and differences on the reports issued by the various laboratories, and perhaps also suggested the requirements and preferences of different markets around the globe,\u201d wrote Mr. Zwaan. \u201cOverall the nomenclature used by laboratories is clear about the nature of the stones described, but there are inconsistencies with regard to the precise terms used, and whether or not grading of synthetic and\/or treated stones is permitted.\u201d<\/p>\n

The special report also provides details about a document prepared by the Gemmological Commission, which it intends will come to serve as a reference point for the industry in the way that it deals with commercial colour terms such as \u201cpigeon blood red\u201d and \u201croyal blue.\u201d Other subjects discussed include how professional opinions can or should be presented separately on laboratory reports, and the necessary standards for governing the use of varietal names for different gemstones.<\/p>\n
