Course Design


The course has been designed in such a way that theory is done online or by correspondence, followed by the 2-day practical (additional) which includes the practical exam at the Gem training venue. On payment you will be enrolled for the course chosen and if an online student a password will be allocated to you so that you can gain access to the course material and questionnaires. If you are a correspondence student, you can collect the course material at our offices, or, if you prefer, we will post the course manual to you. 


The theoretical course material, which comprises 18 sections, each with an assignment which must be completed either on-line or returned for assessment by email. Once successfully completing the course material, you may complete the theory exam online or at the college. A pass mark of 80% is required and successful students will receive a Certificate of Completion. You may then also book a place in an upcoming 2-day practical if so desired.


During the practical , you will be given the opportunity to examine the gemstone species and their varieties  and practice the knowledge you have obtained from the theory module. On the last day you will be given a practical exam. After passing the theory and practical modules, with a minimum pass of 80% you will receive the college Diploma.
