Independently Certified Diamonds
We understand that buying a diamond is a significant investment. That is why each Clean Origin Lab Created Diamond that you buy is independently verified and graded for quality using the same scientific rigor applied to mined diamonds.
We only partner with independent, internationally recognized laboratories, including GCAL and IGI. This gives us (and you!) confidence that the evaluation process is uniform and objective. Here's how it works:
A fully certified, independent diamond grading laboratory evaluates quality by using the stone's unique attributes. These include cut, color, clarity, carat weight, polish, symmetry, and other key characteristics. Evaluators use high precision microscopes and standardized scientific techniques designed for accuracy and consistency.
The laboratory then issues a formal report, grading each attribute in detail. A visual “map” of the diamond further illustrates any inclusions or "birthmarks" that were formed during the creation of the diamond. This report includes a unique identification number and accompanies your diamond.
For added peace of mind, our center diamonds also feature a microscopic inscription of the unique identification number on the girdle of the stone. This laser inscription can only be seen under magnification and in no way impacts the beauty of the diamond. Because it never wears off, it functions like a VIN for your Clean Origin Lab Created Diamond - a guarantee that the stone you buy today is the same one on display years from now.
