Botswana is expanding opportunities for practical diamond education through a collaboration between the Harry Oppenheimer Diamond Training School and STARGEMS Diamond Training Institute in Gaborone. The initiative focuses on developing local talent through specialised rough diamond evaluation training and strengthening technical skills within Botswana’s diamond industry.

The practical programme gives trainees experience working with natural rough diamonds and learning how to assess key characteristics, including colour, clarity, carat weight and cut potential. Participants also gain an understanding of the evaluation process and how it informs decisions about a diamond’s potential value and manufacturing possibilities.
