The determination of a gemstone’s geological age represents one of the most sophisticated areas of gemmological research. At the Gübelin Gem Lab, this work combines advanced isotopic analysis and radiometric dating techniques with mineralogical expertise to establish when a crystal formed within the Earth. 

Age determination provides valuable scientific context for origin studies and contributes to a more complete picture of gem genesis. Through this pioneering research, the lab extends the boundaries of traditional gem identification, transforming gemstones from aesthetic objects into natural records of geological time. The initiative underscores the lab’s enduring commitment to exploration and knowledge within the earth sciences.
