CIBJO, the World Jewellery Confederation, the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA) have agreed to harmonize the nomenclature used by the International Diamond Council (IDC) and CIBJO’s Diamond Blue Book.
According to a press release, “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 organisations”.
CIBJO Diamond Commission President Udi Sheintal explained: “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”. CIBJO President Gaetano Cavalieri added: “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”. The creation of a single universally applicable book “will combat any confusion in the market about nomenclature”, said WFDB President Ernie Blom.
