Certificate program

The program includes two online tests, a final practical diamond exam (requiring the preparation of complete lab reports for four diamonds), a 100 multiple-choice question theory exam, and a five-question essay exam at the end of the course.

The theory exams can be taken online, and in real conditions, as if you were a gemmologist: a gemmologist can refer to a book if in doubt. It will be the same process during the exam. What counts in the WGF exams is the relevance and accuracy of the answers given. We prepare you for this throughout the training.

This is not the case for exams that require essay answers. No reference material is permitted. This exam requires supervision. We strongly recommend that you take this exam at the EGM to make it as easy as possible for you. You also have the option of taking this exam at another academy, or under the supervision of a professional gemmologist to whom we will refer you (you will need to charge $20 per exam hour).

Upon completion of this program, graduates will receive the Diamond Professional Diploma.

This training is part of the Career Gemmologist Diploma Program: therefore, students who hold (already or later) the Coloured Gemstones Professional Diploma will also receive the Career Gemmologist Diploma, without having to take an additional exam since all the requirements have been met.

You will find all the information you need about the WGF courses and the different procedures on the Gem Academy of Canada page.
