WHAT WE DO
WHO WE ARE

Since 2012, DIS has been at the forefront of diamond identification technologies, synthetic diamond documentation, finished jewelry grading, and other pioneering services designed to assist elite jewelry professionals. Our proprietary technologies ensure that every diamond and gemstone is accurately identified as naturally mined, lab-grown, or a simulant. Our reports are trusted worldwide by gemologists, suppliers, and retailers for their unmatched reliability and precision, making them essential for any fine jewelry transaction.

DIS is the only lab to have received the JNA Award twice, in 2014 and 2019. We are also the first company to identify a quarter of a point diamond in jewelry, and our research department regularly publishes groundbreaking discoveries, such as the removal of fluorescence from diamonds. We were the first to explain and demonstrate this process, which, when integrated with other technologies, enhances the accuracy of desktop machines in providing reliable results.
