Nowadays, consumers have much higher expectations for the authenticity and traceability of a diamond. To this end,
Chow Tai Fook deployed innovative technology such as patented nano-inscription to empower our customers.
Each T MARK diamond is inscribed with a set of unique serial numbers, allowing customers to identify the diamond and retrieve its record from procurement to manufacturing. Chow Tai Fook turned a diamond’s life journey into a reliable and unique marking, which is made possible by the Group’s agile business model and decades of expertise and innovations.
T MARK is a traceable promise of natural diamonds safeguarded by technology and global standards. The integrity and traceability of its diamonds have been verified by the world’s leading inspection, verification, testing and certification third party, SGS. And T MARK diamonds have also been assured for consumer confidence in the diamond industry in accordance with the international standard of ISO 18323:2015.
