Our specially constructed Gemology course provides students with a thorough professional understanding of the sorting and evaluation of diamonds. Students receive extensive theoretical knowledge while the practical part of the course gives a hands-on approach to sorting and evaluating diamonds accurately, quickly and professionally.

Sorting is done according to four criteria generally accepted in the international diamond trade established by the Gemological Institute of America - GIA - the 4C's: carat (weight) clarity (cleanliness), color, and cut.

The course takes place in our new and spacious classrooms in the Israel Diamond Exchange complex in Ramat Gan.
