Hong Kong-based jewellery retail giant Chow Tai Fook Jewellery Group Limited has developed its own AI Diamond Grading Certificate powered by state-of-the-art artificial intelligence (AI) and blockchain technology.
The company stated: “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.”
The grading results will be presented in the form of numeric values and Chow Tai Fook will use AI and big data to analyse the colour and clarity of diamonds. “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 company said.
In order to ensure the consistency of grading results, the AI engine developed by Goldway Technology Limited has used deep learning to analyse more than 20 million pieces of multi-perspective diamond images so far. The process takes only a few minutes and greatly enhances the cost-efficiency of diamond grading.
The new certificate will first be available only for T Mark diamonds weighing 0.30 carat or below, in Hong Kong and Mainland China in the first half of 2021.
“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 the aid of a 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.”
