The principle mission of the DCLA is to protect diamond consumers, and consumer confidence, when buying diamonds, providing accuracy, consistency and transparency in diamond grading.

The Diamond Certification laboratory of Australia is equipped with the most advanced diamond technology and equipment in Australia.

All diamonds submitted to the DCLA laboratory are individually identified and tested to International Diamond Council standards, ensuring that the diamond has not been treated or enhanced in any way, and are of natural origin.

The DCLA Certificate identifies the diamond is a natural diamond or a man-made synthetic diamond before it is sold by the trade to consumers.

Independent, Consistent & Accurate Diamond Assessment

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