Leading diamond industry organizations The World Federation of Diamond Bourses (WFDB), The World Jewellery Confederation (CIBJO) and the International Diamond Manufacturers Association (IDMA) have fulfilled the final stage of an agreement, by which the nomenclature used by the International Diamond Council (IDC) will now be harmonised with that of CIBJO’s Diamond Blue Book, creating a single standard for diamond and jewelry nomenclature. The agreement was formalised at the 2017 CIBJO Congress in Bangkok, after the CIBJO Diamond Commission approved amendments to the CIBJO Diamond Book that had been requested by the IDC, as part of the agreement between the three organizations. “The CIBJO Diamond Book may now function as the single official reference book for nomenclature in the entire diamond and jewellery industry, with the goal of enhancing consumer confidence,” explained Udi Sheintal, the CIBJO Diamond Commission President.
CIBJO’s position is that diamonds, which are sold without any qualifier, can be assumed to have been formed in nature. Meeting at the CIBJO Congress last year, the Diamond Commission decided that the CIBJO definition of a diamond would also have the following addition: “a diamond is a mineral which has been formed completely without human interference. It may be subsequently cut and polished.” Synthetic diamonds, therefore, need to be disclosed as such. Article 3.7 of CIBJO’s Diamond Book states: “The fact that a synthetic diamond is wholly or partially synthetic shall be disclosed. Only the term ‘synthetic,’ ‘laboratory-created’ or ‘laboratory-grown’ shall be used to describe synthetic diamonds and these terms shall be equally as conspicuous and immediately precede the word ‘diamond.’”
CIBJO President Gaetano Cavalieri yesterday said, “The true beneficiaries of this agreement are the diamond consumers, who will now be able to refer to a single set of rules for describing diamonds. Our Blue Books are living documents, which are reviewed year in and year out on a continuing basis, to ensure that they are current with changing conditions and technological developments. The fact that the CIBJO Diamond Book now endorsed by the WFDB and the IDMA, serves the interest of both the industry and the marketplace." WFDB President Ernie Blom added, “This is a major step forward that we have worked towards for a long time. The IDC was created by the WFDB and the IDMA to defend the integrity of the diamond, and the step of creating a single, universally applicable book will combat any confusion in the market about nomenclature.”
