International Diamond Council

In 1975, The World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (lDMA), appointed a Joint Committee to create an international standard for rules, working methods and nomenclature.

A comprehensive system of rules and methods was built up, combining the practical experience of professional diamond people with scientific facts and figures.

The Committee later changed its name to the International Diamond Council (IDC). In May 1978 the "International Rules For Grading Polished Diamonds” were unanimously approved at the 19th Congress of the World Federation of Diamond Bourses and International Diamond Manufacturers Association.
