This Monday, ALGT’s General Manager and Chief Gemologist, Marc Segers, was invited by Sofie Vanheukelom, President of Studio Goudmijn, to give a lecture at Kasteel van Bokrijk in Belgium.
Studio Goudmijn is a professional community and educational institution for jewelry designers and goldsmiths in Belgium. Marc’s presentation offered Belgian goldsmiths and jewelry designers a clear insight into how a gemstone testing laboratory identifies gemstones and determines possible treatments.
During the lecture, Marc explained the role of different gemological instruments and how their results are interpreted by gemologists. He discussed how observations such as inclusions, chemical composition, spectral features, and other analytical data can support conclusions on gemstone treatment and, in certain cases, origin determination.
In the afternoon, INFINITY GEMS and Metro Stones, two gemstone companies, also shared their perspectives on the gemstone market from the dealer’s point of view. They additionally organized two hands-on gemstone workshops, focusing on sapphire and emerald, as well as garnet and spinel.
The event was a great success, bringing together education, market insight, and practical gemstone experience. We were delighted to see such strong engagement from the audience and to contribute to this inspiring professional exchange.
