Certifications and laboratory technology

All our diamonds are verified and certified by the 3 most renowned diamond grading laboratories in the world: IGI, GIA, and HRD. These certifications are recognized worldwide and attest to the value of the stone. Furthermore, all our jewelry and, in particular, the raw materials we use, undergo multiple quality tests. These tests include the use of the "G-Certain synthetic diamond detector" and integrated CAD/CAM systems that closely monitor production, along with the expertise of our Italian goldsmiths and setters, who boast the highest competence in the industry.

Our mission is to provide a quality product through advanced and innovative services and equipment. Our selectors are passionately dedicated to their work, constantly utilizing and seeking the most modern diamond evaluation technologies. This personal touch, complemented by our advanced and technological processes, ensures the highest levels of accuracy and consistency. CR Gioielli has established high standards of quality and craftsmanship for diamonds, aiming to honor the commitment to every customer. Being products of nature, the diamonds we use defy every quantification and categorization in absolute values. Thanks to our clear definitions of the 4Cs characteristics, we achieve high levels of accuracy and consistency in the standard. The purchase of our diamonds respects the Kimberley Process, an international initiative that ensures the profits from their trade do not finance civil wars, thus ensuring conflict-free diamonds. A rigorous Warranty System confirms that our stones are completely unrelated to any armed conflict, verifies their path, and requires scrupulous compliance with correct procedures by all producers and traders. CR Gioielli's diamonds not only respect the dignity of those who extract them, but they are also a legal source of employment for many people. For us, there is no value without legality and transparency. CR Gioielli exclusively chooses Natural Geological Diamonds, controlling each stone with the best technologies available on the international market.

Our diamonds undergo meticulous individual testing before entering the production, distribution, and sales chain. This ensures that they are 100% natural and free of any treatment, both before and after cutting, as well as completely exempt from laboratory synthesis processes. To this end, after conducting various tests with different equipment available on the market, we have opted for what is undoubtedly the most innovative and accurate equipment for controlling natural geological diamonds currently available, the G-Certain, designed, tested, and manufactured by Massive Tech Lab. This equipment is a Synthetic Diamond Detector, used to identify synthetic materials. It is capable of recognizing laboratory-grown synthetic diamonds, both through CVD and HPHT methods, proving effective with all sizes, shapes, and colors of diamonds.
