A diamond certificate gives you a full detailed description of the diamond(s) you are buying. It gives the buyer a guarantee of the quality of diamond they are buying.

In 1975, the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA) appointed a joint committee to create an international standard for rules, working methods and nomenclature. The results were that in 1976, a comprehensive system of rules and methods was built up, combining the experience of professional diamond people with scientific facts and figures. That joint committee is now the International Diamond Council (IDC) which, in 1978, presented the result of their efforts at the world congress of WFDB and IDMA: the International Rules for Grading Polished diamonds.
