Beside the regular courses that the Harry Oppenheimer Diamond Training School present, H.O.D.T.S. also invite the G.I.A. (Gemological Institute of America) to present their courses at our premises. Since 1998 they have sent highly qualified lecturers to present various courses like Diamond Grading, Coloured Stone Grading and Gem Identification.

We will invite them to present courses possibly during August. Details will be published here when available.

Students can enrol for the G.I.A.'s distance education programs and do the practical side of the course at H.O.D.T.S.
