During these evenings our expert gemologist will lead us through the fascinating world of precious stones, everything we always wanted to know about gems, but never had the opportunity to find out. We will explore different analysis instruments, touch some very precious stones, discuss the characteristics of different gemstones, learn about their value, learn about synthetic and imitation stones. We will test our new knowledge in a series of small tests and get the pleasure of winning unexpected prizes. A very interesting course full of challenges. Expect to spend about € 30 for supplies. Make up for missed classes: 3 sessions maximum. Max 10 students admitted/course. This course is available twice a year


Three seminars about gemological analysis and gemological know- how. Nine monographic lessons about: diamond, corundum (ruby and sapphire), beryl (emerald and aquamarine), pearl, quartz and tourmaline, garnet, turquoise, and other semi-precious stones as requested by the students.
