Chow Tai Fook Jewellery Group Limited (“Chow Tai Fook Jewellery Group”, “the Group” or “the Company”; SEHK stock code: 1929), a Hong Kong Main Board listed company with over 90 years of heritage, is pleased to announce the successful development of Chow Tai Fook AI Diamond Grading Certificate powered by state-of-the-art artificial intelligence (“AI”) and blockchain technology. This Certificate, soon available in the market, aims to offer a highly consistent and truthful diamond grading standard plus an extra natural diamond quality assurance to customers.

Revolutionising the current industry practice, Chow Tai Fook uses AI and big data to analyse the color and clarity of diamonds, and presents the grading results in numeric values. This not only helps customers understand better the grading and interpret the characteristics of diamonds; minimises the risk of human errors in grading results; but also provides extra diamond quality assurance to customers. The AI technology is developed by Goldway Technology Limited. Garnered six international invention patents covering system design, operating process and AI analysis, etc., the AI-empowered system provides a highly controlled grading environment and stable analysis performance, thus avoiding inconsistent results caused by subjective or environmental factors. In order to ensure the consistency of grading results, the AI engine has used deep learning to analyse and learn from more than 20 million pieces of multi-perspective diamond images so far. The process takes only a few minutes that greatly enhances the cost efficiency of diamond grading.

The initiative will first be available for the diamonds (0.30 carat or below) of T MARK, the Group’s diamond ingredient brand, in Hong Kong, China in the first half of 2021, demonstrating an objective 4Cs grading result and T MARK natural diamonds’ 4Ts guarantee alike.

Chow Tai Fook Jewellery Group Managing Director Kent Wong remarked, “Our innovative DNAs anchored in our corporate culture has all along steered us to pioneer in the jewellery industry, and continuously supported the industry towards its sustainable development through digital empowerment. We actively develop the AI technology in diamond grading arena and once again set a new standard for the industry.”

“As always, T MARK strives to offer customers a comprehensive experience on diamond appreciation by leveraging innovative technology,” said Chow Tai Fook Jewellery Group Executive Director Bobby Liu. “This time, with an aid of digital and scientific solution, the value of a diamond is redefined by offering a different experience of diamond appreciation in quality. Moreover, the Chow Tai Fook AI Diamond Grading Certificate is securely written on blockchain and integrates seamlessly into the CHOW TAI FOOK T MARK app, allowing customers to access both their diamond’s traceability and grading information at their fingertips through a single digital platform.”
