DCLA & The International Diamond Council (IDC)

The International Diamond Council (IDC), established in 1975, is a globally respected authority in the diamond industry, created to regulate and support the ethical trade of diamonds worldwide. Formed through a partnership between the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA), the IDC plays a central role in upholding the integrity, transparency, and technical standards of the global diamond market.

A major milestone in the IDC’s history is the launch of the International Diamond Grading System (IDGS) in 1978. This system introduced a universal, objective method for evaluating diamonds based on the 4Cs—Carat, Clarity, Colour, and Cut—which remains the international benchmark for diamond grading and certification.

The IDC is also deeply committed to combating the trade of conflict diamonds, also known as blood diamonds. By working closely with governments, NGOs, and industry bodies, the IDC promotes the responsible sourcing of diamonds, ensuring ethical practices throughout the supply chain and protecting human rights.

In Australia, the Diamond Certification Laboratory of Australia (DCLA) is the only IDC-accredited diamond grading laboratory, holding exclusive rights to the nation’s National Diamond Masterset (C2Au). As Australia’s only CIBJO-recognised grading laboratory, DCLA strictly follows IDC standards, offering independent, internationally recognised diamond certification that builds consumer trust and confidence.

The IDC’s leadership in diamond grading accuracy, ethical sourcing, and consumer protection ensures diamonds remain a trusted symbol of love, value, and beauty for generations to come.
