Holding a major role in the world of jewellery, gemology laboratories allow merchants, auction houses, and jewellery brands to authenticate their stones, determine their purity, origin, and thus set their value.

Employed for these analyses, artificial intelligence is an increasingly used tool: “The project began in 2020. We trained our software for two and a half years and have been applying it concretely for six months,” explains Daniel Nyfeler, General Manager of Gübelin Gem Lab. “Artificial intelligence does not allow us to improve our research per se, but the consistency of the results. A data set will not be interpreted the same way by several different experts, while AI will always provide the same interpretation,” he clarifies.

For Laurent Cartier, attached to the Swiss Foundation for Stone Research, it is also a means to better organize and visualize the thousands of chemical and spectroscopic data present in the stones to “better identify them, and understand how they form.”

A round table is thus organised on the occasion of GemGenève to present the challenges, advancements, and potential for research in gemology.
