Standard European nomenclature for synthetics

In mid-November, the CIBJO Europe Working Group convened a meeting in Antwerp, with its objective being to come to an agreement on nomenclature for synthetic diamonds. CIBJO Europe is a body that was created by the World Jewellery Confederation in 2007 to promote standard diamond terminology in the European Community. It is strongly supported by a consortium of the major diamond producers, including De Beers, Rio Tinto and BHP Billiton.
