Analysis & Publications
Analysis
Scientific analysis is central to the Gübelin Gem Lab’s mission of providing trustworthy and reliable gemstone reports. Combining classical gemmological testing with cutting-edge analytical techniques, each sample is examined to reveal its identity, authenticity, potential treatments, and – where possible – the country of origin. Methods such as spectroscopy, chemical element analysis, and advanced imaging allow for reliable determination of the relevant parameters of each item.
This analytical work supports the lab’s wider goal of contributing to scientific progress within the field of gemmology. The accumulated data from decades of research not only enhances report accuracy but also deepens the collective understanding of gemstone formation and provenance. Every analysis undertaken reflects the lab’s dedication to methodological rigour, innovation, and objectivity.
Publications
For more than a century, the Gübelin Gem Lab has shared its insights through scientific and industry publications. These works document advances in analytical methods, developments of novel methods of data interpretation, case studies on gem origins, and discoveries in the mineralogical sciences. Each publication reflects the lab’s commitment to open exchange within the global gemmological community and to fostering transparency in the trade.
The lab’s researchers regularly contribute to peer-reviewed journals, conferences, and collaborative studies, helping to establish new standards for gemstone testing and reporting. Through these publications, the Gübelin Gem Lab continues to uphold its role as both a laboratory of record and a source of trusted scientific knowledge.
