FOCUS 焦点 10 | JNA July/August 2025 From artificial intelligence (AI), provenance and traceability programmes to innovative diamond solutions, the gem and jewellery industry is embracing technology to enhance operations, offer sophisticated services and meet customer requirements. Gübelin Gem Lab blazes a trail in leveraging new technology, adopting AI and developing traceability platforms long before these were fully embraced by the trade. And it is not resting on its laurels as it continues to expand the capabilities of its groundbreaking initiatives. Its AI-powered Gemtelligence, launched in February 2023, can determine the origin of rubies, blue sapphires and emeralds and identify heat treatment in rubies and blue sapphires. The system is integrated in all the lab’s testing protocols in its operations in Lucerne, Hong Kong, New York and Bangkok as well as its mobile laboratories. Every Gemtelligence result though undergoes a plausibility check from a senior gemmologist before it is released. Gemtelligence was trained on a combination of coloured gemstones from the Gübelin Reference Stone Collection that has over 30,000 stones of high authenticity, and a carefully curated selection of client stones received over the course of more than 100 years. The lab’s database is continually updated and expanded with stones from its field trips, most recent ones being to Tanzania, Vietnam, Pakistan and Madagascar. Together with the Gübelin Academy, the lab also acquired a collection of more than 1,800 reference samples from its former head of Research, Dietmar Schwarz. After careful analysis and scrutiny, this was likewise included in the training data. Significant gains While the most immediate impact of Gemtelligence is greater consistency of results in lab reports, the system also manages to retrieve more information from less data, according to Gübelin Gem Lab Managing Director Daniel Nyfeler. “In some cases, this allows us to shorten the testing protocol. For some stones, we can forgo certain timeconsuming microscopic description and/or the expensive chemical analysis by Laser Ablation ICPMS,” he noted. These efficiency gains and cost savings prompted Gübelin Gem Lab to offer the streamlined Gem Passport service and even open a location in Bangkok.
