Internationalization of the Fei Cui Standard

Dr Shang I (Edward) Liu (left), Dr Gaetano Cavalieri (middle) and Mr Kent Wong (right) at the CIBJO Congress 2019 (Bahrain) 

A Fei Cui special session at the CIBJO congress 2019 (Bahrain) was held and presented by the Dr Shang I (Edward) Liu (Vice-Chairman of the Gemmological Association of Hong Kong) and Mr Kent Wong (Managing Director of Chow Tai Fook Jewellery Group and Chairman of the HK Jewellers’ & Goldsmiths’ Association) as representatives of the GAHK and the Jade industry. Comprehensive scientific studies have resulted in a new definition of jade. It has, therefore, been suggested that the term “Fei Cui” should replace “Jadeite” as a family name under the umbrella term “jade”, covering the three members: jadeite jade, omphacite jade and kosmochlor jade. “With a market size that is comfortably in excess of $8 billion per annum, ……it is fair to say that, after diamonds, Fei Cui products make up the most valuable sector in our worldwide industry. ……It needs to be properly addressed within the CIBJO system.” the CIBJO President Dr Gaetano Cavalieri stated in his opening address. CIBJO is currently considering the proposal that “Fei Cui” should be included in their Blue Books. It becomes a milestone as “Fei Cui” entering the international arena.
