The DCLA is one of a growing number of diamond grading laboratories worldwide grading to the International Diamond Council (IDC) rules, (WorldFed Newsletter, Edition 6, August 2003, Page 8). The IDC is the governing body established by the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA). These two bodies are the worlds highest Authorities in Diamonds.
DCLA is the only CIBJO Diamond Grading laboratory for Australia and holds the only official registered National Diamond Masterset for Australia, the C2Au set.

Protecting Diamond Buyers

The DCLA Diamond Grading Laboratory Certificate sets the standard for technical ability. The laboratory is equipped with the most advanced equipment in Australia. All diamonds graded are checked and tested to ensure that they have not been treated and are of natural origin. Therefore the DCLA Diamond Grading Certificate assures the owner that the diamond is free of all known diamond treatments and enhancements. It also confirms that the diamond is natural and not a synthetic diamond. DCLA cold laser inscription links the diamond to the certificate providing added confidence.

Independence means that the DCLA Diamond Grading and Certification Laboratory is autonomous from all diamond and jewellery businesses. The DCLA Laboratory receives no grants or funding from the diamond or jewellery trade, it is completely self funded.

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. All the major diamonds laboratories have since adopted the system. DCLA is proud to offer a diamond certificate with such pedigree.

The diamond trading floor that gives all diamond buyers direct access to DCLA guaranteed diamonds from Australian diamond dealers.
