It was also the start of my career in the diamond industry, looking back 8 year later, they are the best you can't go wrong also remember the GIA Courses they offer are very benefical.

It was super great coming to your school. The teaching and the information was life transforming. The discussion was something truly special.

We are indeed impressed with the valuable contribution that your training facility is making to the Southern African Diamond Industry.

I attended multiple courses on diamonds and coloured gemstones under the guidance and instruction of Koos Rademeyer, which greatly enhanced my skill in gemology, as well as the diamond and gemstone trade. The rough diamond evalaution course isa credential that has proved benefical to me in my business dealings in the diamnd industry.

In 2014 i did the polishing course. It was extremely professional and educational. The best part is that it is practical and you get to polish real diamonds. The teachers are extremely knowledgable and freely pass their knowledge .

Thank you for the oppertunity to attend the rough diamond evalaution course at HODTS. My two colleague and myself thoroughly enjoyed the course and believe we are now equipped with the knowledge to add significant value to Alexkor diamond sales

The past 2 weeks with you guys was the best ever in my life. Thank you for your commitment to empowering us.

It is such a beautiful course. I am very proud to have achieved such an insightfull course at the Harry Oppenheimer Diamond Training School
