The International Diamond Council (IDC) was established in 1975 by the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA) to create an international standard for rules, working methods and nomenclature.
Antwerp, Belgium – April 4, 2011: The International Diamond Council (IDC) announced today that it has completed the German translation of the "IDC Rules for Grading Diamonds" and has uploaded a PDF file of the German-language version on the organization's website. The file can be downloaded at: www.internationaldiamondcouncil.org.
The IDC was established in 1975 to provide its founders – the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA) – with a set of universally accepted standards of nomenclature for polished diamonds within the international diamond trade. The challenge for a clear and unambiguous description of a polished diamond characteristics and quality was taken up by the IDC. At that time, it was mostly a 'horizontal' interest, meaning that is was of interest predominantly to the diamond and diamond jewellery trade.
