Authenticity and traceability of a diamond are increasingly important from the consumer’s point of view. For this reason, Chow Tai Fook has deployed the patented nano-inscription and immutable blockchain technologies to develop the best industry practices to empower consumers.
T MARK, drawing on the 4Ts concepts of “Transparent, Traceable, Thoughtful, and Truthful”, is a proprietary diamond brand that carries a set of unique serial numbers in the marking inscribed on each diamond.
T MARK allows customers to identify the diamond and retrieve its procurement, cutting and polishing, marking, authentication, design and production records, by turning a diamond’s life journey into a reliable and unique marking, made only possible by the Group’s agile business model and decades of expertise and innovations.
Guided by its pioneering spirit to promote innovation and best practices in the industry, in 2018, Chow Tai Fook further incorporated cryptographically secured blockchain to deliver diamond grading information into the hands of consumers via the T MARK mobile app. The integrity and traceability of T MARK have also been certified by the world’s leading inspection, verification, testing and certification third party, SGS.
