Gemmological training

The opportunity to do gemmological training in the comfort and safety of your own home

By Alan Lowe, Gem Training International

To say that our world has been turned upside down is an understatement. The new “normal” is a far cry from what we all were used to. All businesses have had to re-evaluate and adjust their business models and how they are going to operate to be successful in the changed environment. The necessity for skills, reskilling and/or up-skilling is greater than ever before and we at Gem Training International have spent the last few months re-aligning our courses, adding a new course for jewellers· staff and updating our online portal.

We are now better prepared to assist both the individual and corporate to increase their knowledge and in so doing increase their effectiveness in sales, purchasing, control or managerial functions. The study of gemmology requires in most cases, both the study of theory and the “all important”, practical, where the theory is put into practice and the use of gemmological testing equipment explained and used for the course, whether it be diamonds or coloured gemstones.

The theory modules for all the courses are done online via our e-learning portal that houses all the course material, assessments, and completion certificates. Where connectivity is a challenge, the courses can be done by correspondence. The practical training modules take place in a Covid-19 compliant classroom facility. All the equipment and gemstones necessary for the courses is provided. The course material can be tailored to suit an organizations specific requirement, as can the practical modules. Each course has been designed and structured with a particular objective and outcome in mind:
