CPD Programme and Diamond Certified Gemmologist Registration System


Continuing Professional Development (CPD) is an ongoing necessity in the ever-changing technological world in which we live. The practicing professional gemmologists have to remain competent throughout their working careers so that they can properly carry out various duties and roles in the ever-changing complex environment. To this end gemmologists need to take opportunities to update their knowledge and expertise and to develop those personal qualities required to fulfill their roles in industry and in professional community as well.

In line with the global trends of CPD in leading professional bodies and institutions, The Gemmological Association of Hong Kong (GAHK) has considered that there is a need of implementing the mandatory CPD requirements for “Certified Gemmologist” (C.G.) [認可鑑證師] on specific fields of gemstone testing to instill a sense of professional responsibility amongst gemmologists, to strengthen consumer’s confidence on gemstone identification and certification, and subsequently to uphold our reputation as a leading professional gemmological institution in Hong Kong.

GAHK announced the Mandatory CPD Requirements for Certified Gemmologists in August 2006. GAHK’s “Standard Methods for Testing Fei Cui (Jadeite Jade) for Hong Kong” (HKSM/JJT-2006) and “Standard Methods for Testing Diamond for Hong Kong” (HKSM/DT-2008) were adopted by the Custom and Excise Department as a key reference of the definition of the Fei Cui and Diamond in the Trade Descriptions (Provision of Information on Natural Fei Cui, Diamond) Order in 2009.

The “Standard Methods for Testing Fei Cui for Hong Kong” (HKSM/FCT-2016) was issued in 2016 and the Chinese version of the Standard namely as 香港翡翠標準測試方法 was published in 2018. In 2014 and 2019, the Specification of Competency Standards (SCS) for Testing, Inspection and Certification Industry and the second version of SCS for Jewellery Industry namely as珠寶業《能力標準說明》(第二版)with the Units of Competency (UoCs) of Testing and Certification were announced by the Secretariat of Hong Kong Qualification Framework which is a major initiative by HKSAR Government to support lifelong learning and to enhance the quality and competitiveness of the workforce.

In April 2020, GAHK announced the new Guidance Notes for Mandatory Continuing Professional Development (CPD) for Fei Cui & Diamond Certified Gemmologists.
