Gems &
jewellery

International Diamond Laboratory is an independent international laboratory & research organization specializing in diamond, gemstone, jewellery identification, quality analysis and evaluation.

Dedicated to the
World of
Gemological Science

In IDL Labs Every diamond is tested to identify whether it is natural, Treated, or Lab Grown Diamond. If it is found to be laboratory grown, under disclosed conditions, we will issue a Laboratory Grown Diamond Grading Report, with Full 4Cs assessment and plotted clarity diagram. The laboratory-grown diamond’s girdle is laser inscribed with the term “Laboratory-Grown” and its IDL report number.
