Gemmology 3 and 4

Appearances can be deceiving.  Many gems like red spinel and ruby can, at first glance, appear very similar.  Now that you have learned about the many varieties of gemstones (Gemmology 1) and how to use gem-testing instruments (Gemmology 2), hone your gem identification skills by differentiating and identifying gems that can easily be confused.

Gemmology 3 and 4 are similar courses designed to help students apply their new gem knowledge in practical situations by presenting them with gems grouped by colour and asking them to differentiate and identify each individual material.  

The fall term focuses on purple, yellow, brown, colourless, white, and black gems and the winter term has students examining blue, green, red, and organic gems.



When students have completed Gemmology 1, 2, 3, 4, and the Diamond Grading workshop they can sit the Certificate of Gemmology theory and practical exams.  The theory exam consists of 120 multiple choice questions and for the practical exam students have three hours to test and identify 10 stones.

If you feel like you need a little more practice before sitting the exams you can enroll in Gemmology 5.
