Quality Assurance

The Group exercises strict quality control and is meticulous from raw materials procurement, production to after-sales services. In 1996, China Gems Laboratory Limited ("CGL"), a wholly-owned subsidiary of the Group which is operated and managed by experienced and certified gemologists, was established to provide services including authentication and grading of diamonds, authentication of jadeite jade and coloured gemstones, and quality testing for jewellery. In 2005, CGL succeeded in applying for accreditation by the Hong Kong Accreditation Service and became one of the first accredited laboratories that conformed to ISO/IEC 17025 and obtained the accreditation in jadeite jade testing. Subsequently, in 2009, it obtained the accreditation in diamond authentication and grading. In 2015, CGL obtained ISO 11426 accreditation in gold fineness testing and was authorised to issue internationally recognised gold testing report. It is the only laboratory in Hong Kong that meets the requirements of accreditation in jadeite jade testing, diamond authentication and grading, and gold fineness testing. Besides, it is the first laboratory in Hong Kong to obtain Chinese national standards GB/T9288 accreditation in gold testing, affirming its international level quality assurance system and professionally recognised product quality standard.

 

In 2013, the Group set up Victoria Gemological Institute Limited, which principally engages in jewellery authentication and professional training. With branch offices established in Mainland China, the institute provides services for the jewellery sector and customers. The Victoria Gemological Institute has passed the ISO/IEC 17025 accreditation of the ANSI-ASQ National Accreditation Board (ANAB) and the accreditation of the International Laboratory Accreditation Cooperation (ILAC) and is authorised to issue internationally recognised reports for diamond grading, jadeite jade, ruby, sapphire and emerald testing.

 

In 2015, the Group became a sightholder of De Beers Group and has further demonstrated the Group’s leading position in the jewellery industry.
