Ahead of the 2024 CIBJO Congress in Shanghai, the Gemmological Commission has issued a paper calling for the implementation of universal best practices for gem laboratories globally.
The report recommends that the CIBJO Gemmological Laboratories Blue Book, a comprehensive handbook with over 300 pages, be utilized as a benchmark for gem labs. This could lead to the establishment of an international registry of laboratories that meet these standards.
Many countries currently lack regulatory frameworks for gem laboratories. This may pose a risk to both the industry and consumers. The CIBJO Gemmological Commission intends to address this issue by developing clear criteria for gem laboratories.
The Blue Book is compliant with ISO 17025, an international standard for testing and calibration laboratories. However, it goes beyond this by giving procedures and standards relevant to the gemstone and jewellery sectors.
The study addresses the critical elements for building a dependable and responsible gem lab, such as management practices, technical formalities, and maintaining independence and impartiality. It also describes the different aspects that influence the accuracy and reliability of gem testing and grading.
The Gemmological Commission intends to consider the idea of developing a method to recognise laboratories that meet Blue Book standards. This might include issuing a “CIBJO Acknowledgement of Gemmological Laboratories” and putting them alongside other reputable organizations. A registry like this could help consumers and industry professionals find reliable gem labs.
However, it is crucial to highlight that this acknowledgment does not indicate that CIBJO has verified or endorsed specific results. Individual laboratories continue to be accountable for their own operations.
