Very Accurate Tools and Equipment

We stand by the quality and accuracy of our results. Here at IGL, we use a blend of modern and old technologies to give you the most accurate results.
World Class Standards

Examining the cut and proportions of your investment diamond is a very complex process. At IGL, we use advance computer modelling to closely examine your diamond’s cut and accurately assess its quality.

An IGL Diamond Certificate Guarantees the Value of Your Diamond Investment

For most Australians, buying a diamond is a once in a life-time event. And we understand that this process is full of anxiety as many jewelers in the market tend to rob you of the value you deserve (by using fraudulent means) so just they can profit more.

Our aim is to take that stress and anxiety off you. IGL’s years of experience and expertise in the industry will help you make sure that you are getting your money’s worth in your investment diamond. Once you you have a diamond certification from IGL, you can rest assured that your diamond has been thoroughly tested and graded using the latest equipment and world class standards.
