Hong Kong retailer Chow Tai Fook Jewellery Group Ltd has developed a new diamond grading certificate powered by artificial intelligence (AI) and blockchain technology in collaboration with Goldway Technology Ltd.

The AI Diamond Grading Certificate, to be released in the market soon, will offer customers with consistent and accurate diamond grading standards alongside an “extra” natural diamond quality assurance, according to the company.

Chow Tai Fook uses AI and big data to analyse the colour and clarity of diamonds. The results will be presented in numeric values, which helps customers better understand and interpret the grading while minimising the risk of human errors. 

The AI technology, developed by Goldway Technology Ltd, garnered six international invention patents covering system design, operating process and AI analysis, among others. It provides a highly controlled grading environment and stable analysis performance. The process takes only a few minutes, enhancing the cost efficiency of diamond grading.

This service will first be available for T MARK diamonds (0.30 carat or below) in Hong Kong in the first half of 2021.

Chow Tai Fook Jewellery Group Executive Director Bobby Liu commented, “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.”
