Standard Methods for Testing Fei Cui for Hong Kong (HKSM/FCT-2016)
In February 2016, GAHK issued and published the English version of the "Standard Methods for Testing Fei Cui for Hong Kong" (HKSM/FCT-2016). This Standard is to provide local gemstone testing laboratories with technical specifications to classify a Fei Cui test item (which has met the definition of Fei Cui and Natural Fei Cui specified in the Trade Descriptions Ordinance) known as Type A, Type B, Type C or Type B+C. The Chinese version of this Standard was also issued in September 2018. Public can freely view and download the bilingual version of this Standard from the new GAHK Feicui website.
