Diamond bodies clarify labeling of synthetic gems

Three major international trade organizations in the diamond and jewelry industry reached an agreement to abide by the new International Diamond Council (IDC) rules, particularly regarding terminology of synthetic diamonds, at the thirty-third World Diamond Congress in Shanghai.

The three organizations were the International Confederation of Jewelry, Silverware, Diamonds and Stones (CIBJO), the World Federation of Diamond Bourses (WFDB), and the International Diamond Manufacturers Association (IDMA).

The revised IDC rules included terminology that broadens the range of descriptors that can be used for gem-quality diamonds that have been created in laboratory or factory, and to date have been referred to as synthetic.

According to the new IDC rules, gem quality diamonds created in a laboratory or factory can be described as: synthetic; laboratory-grown; laboratory-created; or man-made; and the descriptor must always be followed by the word diamond or diamonds.

It was agreed that under no circumstances could the term ‘cultured' be used to describe gem-quality synthetic diamonds. At present, the International Confederation of Jewelry, Silverware, Diamonds and Stones' (CIBJO's) Diamond Blue Book only allows the descriptor ‘synthetic' to describe gem-quality synthetic diamonds.

"Concerning diamond nomenclature, we have been aiming to get IDC in line with the CIBJO for many years. This important achievement bodes well for the development of the future of international diamond grading standard and nomenclature," said IDC Chairman Stephane Fischler, who lauded the statement from the organizations as a milestone event.

Since their publication, the IDC stated that these rules have been the essential reference point for clear diamond terminology aimed at benefiting consumer confidence in diamonds.
