Sarine Partners With NGTC on Grading Reports In China

Sarine Technologies and China’s National Gemstone Testing Center (NGTC) will introduce co-branded grading reports and services for the mainland China market.


According to Sarine, the reports will establish a new industry standard for light performance in China market. For the past two-and-half years, NGTC has been carrying out extensive tests on diamonds of various cut qualities using Sarine’s technology including DiaMension® HD and Sarine Light™ following a 2019 agreement to co-develop new testing guidelines for China. The lab then worked on improving internal testing methods and data collection and analysis, alongside regular communication with Sarine.


The new standard based on Sarine Light™ device expands diamond classification beyond the standard 4Cs to offering information on brilliance, fire, sparkle and light symmetry. 


The alliance between Sarine and NGTC will create a new experience for diamond retailers and consumers, heighten transparency and facilitate a more robust diamond consumer market, said David Block, CEO of Sarine Technologies.
