Career Gemmologist

Do you want to become a professional gemmologist and hold a world-renowned diploma? That’s what the Career Gemmologist program offers you: gemstone science, identification and grading of coloured stones and diamonds are at the rendezvous.

The Career Gemmologist Diploma, developed by the WGF (World Gem Foundation), aims to train gemologists with a solid knowledge of fundamental gemmology, but also with expertise in diamonds and coloured stones: three areas of expertise in one diploma!

Organization of the courses

The WGF courses have the great originality of being built by “independent” courses. Thus, two solutions are available to you: you can access the Career Gemmologist Diploma by taking your time, courses by course, or by choosing the Career Gemmology Module.

The Career Gemmologist Diploma course by course:

This formula allows you to:

  • Choose the course format that suits you best course by course (printed or digital version)
  • Adapt more easily your pace of study to your lifestyle
  • Spread out your payments (payments are made course by course, at the beginning of each course), and adapt your learning to your finances.

However, this flexibility requires:

  • A great deal of discipline
  • A good personal organization (courses must be followed in a given order)
  • Respecting the prerequisites (in order to get the most out of each course).

If you choose this formula, the first course to follow is Basic Gemmology.

The Career Gemmology Diploma with the Career Gemmology Module:

This formula offers two advantages:

  • As the Career Gemmology Module consists in the five theory courses, you can’t go wrong with the order of the lessons…
  • You pay for all these courses at once, but the price is more interesting.

Before you register for your first lesson, we ask you to send your CV and cover letter to We will offer you an interview via Skype or Whatsapp or on-site. The aim is to make sure that you have chosen the right training, and we’ll be able to answer all your questions.

Please, be aware that these studies require seriousness and involvement. The level of the courses is indeed high, and requires a significant personal investment in terms of learning and revision time.

Language and schedules

The course is given in English.

It is also available in French. To register, please go to the French page of the course: Gemmologue de Carrière.

If you wish to follow the theoretical courses in Spanish (online and digital version only), please contact us at We do not give practical workshops in Spanish.

As the courses are given online, you will start and complete your course at your own pace. Make sure to respect the order of the classes.

If you want to benefit from a more intensive training and thus optimize access to the workshops (which are given in successive order), we advise you to start the training at least four months before the start of the first workshop. This implies a fairly dense rhythm. If you need more time, start earlier. The first workshop is Gem Identification 1 (the starting date of the workshop is indicated on the page of this course).


Prices will differ depending on the formula you choose. For example:

  • The least expensive formula will be the totality of the theoretical courses on a digital version with the practical workshops at EGM: $11,238.81 CDN (taxes included)
  • If you choose to take this training course by course, with a printed version, the final amount will be $11,957.40 CDN (taxes included)

Certificate program

This program consists of twelve online tests, a final practical exam on coloured stones (consisting of twelve stones), a practical exam on diamonds (requiring the preparation of complete lab reports for four diamonds), a theoretical exam of 100 multiple-choice questions and a theoretical exam of five essay questions.

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

This is not the case for exams that require essay answers. No book searches are 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).

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