At the core of GCI’s activities is the commitment to education. We believe in the power of education as an asset for
self improvement and to further one's own career.
Tailor made courses given in 10 different languages, by GCI’s experienced gemologist and teachers of gemology, will
not only teach you theoretical specific knowledge, but will also provide you with valuable experience towards its
practical applications. The courses at GCI allow participants to become more familiar with precise grading, identifying
diamond treatments, simulants, synthetic diamonds, rough diamonds and much more.
The classes are equipped with all the necessary up to date gemological testing equipment, to which all students have
individual access. Teachers adapt the courses to the students' individual learning levels, with a specific interest
in bringing out the excellence of each student in the field they have selected
