During the early 1980s, the Hong Kong jade market was flooded with chemically treated and resin impregnated Fei Cui (known as Type B in the industry). It was difficult to distinguish Type B from Type A (Natural Fei Cui) by standard gemmological testing and consumers' confidence was affected. Therefore, the Hong Kong Jewellery & Jade Manufacturers Association (formerly known as the Hong Kong Jade and Stone Manufacturers Association) established the Hong Kong Jade & Stone Laboratory Ltd. (HKJSL) in 1993. Equipped with the most advanced instrumentation, including an infra-red spectrometer, the experienced gemmologists of HKJSL can test Fei Cui accurately and issue authenticated certificates to the public.

The HKJSL carries out Fei Cui testing and certification services in an impartial and objective manner, enabling both consumers and jewellery traders to have a clear understanding as to whether their Fei Cui is natural or treated.


Other than jade, the authentication service of the HKJSL had extended to ruby, sapphire, emerald and diamond in 1997.

In 2001, the Hong Kong Jade Association joined venture with the Hong Kong Jewellery & Jade Manufacturers Association to set up a HKJSL ( Kowloon Branch ).  As these two partners did not involve into any jewellery sales activities, therefore their authentication service was guaranteed independent and impartial.

In 2004, the HKJSL entered The Hong Kong Laboratory Accreditation Scheme (HOKLAS) of the HKSAR Government.  Before the final assessment, the HKJSL spent 2 years in planning, amending and repeated testing to ensure their authentication system could meet the global criteria in terms of stability and reliability.  Eventually, in Feb 2005, the HKJSL was awarded as an accredited physical & mechanical testing plot ( HOKLAS No. 153 ).  Moreover, recently it was also recognized by the International Laboratory Accreditation Cooperation (ICLA) and awarded with an ( MRA ) sign.

Internationally, the Hong Kong Jade and Stone Laboratory is recognised by the World Jewellery Confederation, CIBJO (Confederation International de la Bijouterie, Joaillerie, Orfevrierie des Diamantes, Perles et Pierres), and has been designated as the Official CIBJO Registered Laboratory for Hong Kong.
