Gübelin Gem Lab Taps AI For Coloured Gemstone Grading

Celebrating its 100th anniversary, Gübelin Gem Lab launched Gemtelligence, a new software which ensures consistency in analyses of coloured gemstones and determines the origin of emeralds, rubies and sapphires using artificial intelligence (AI) and deep learning.


The new tool was created in cooperation with technology and innovation institute the Swiss Center of Electronics and Microtechnology (CSEM). Gübelin Gem Lab announced it at AGTA GemFair Tucson earlier in February 2023.


Gemtelligence uses an algorithm based entirely on AI to pinpoint the country of origin of emeralds, rubies and sapphires, and heat treatments in rubies and sapphires. It is a first in the gemstone industry, according to the Swiss gem lab.


The system, which employs deep learning architecture, references the Gübelin Gem Lab’s archive of more than 28,000 gemstones from all commercially relevant mines, along with tens of thousands of high-grade stones the lab has analysed for customers since the 1970s.


Gübelin Gem Lab said: “This progress makes it possible to fully delegate data interpretation to a software program. Gemmologists are free to increasingly concentrate on producing plausible results, leaving them more time to invest in research and development.”


Gemtelligence is being successfully implemented step-by-step in Gübelin’s three laboratories in Lucerne, Switzerland; Hong Kong and New York. Currently, each gemstone in these locations is still being tested by human experts.


Daniel Nyfeler, managing director of Gübelin Gem Lab and project manager for Gemtelligence said: “The fascinating aspect of this project is not just the improved precision and consistency of the data evaluation but also the ability to simply dispense with time-consuming and expensive analyses. This is something the entire industry will profit from.” (Photo courtesy: Gübelin Gem Lab)
