General Interest Gemmology and Jewellery Classes

General interest courses are for persons who want to learn more about gems without undertaking professional training.  Pre-registration is required for these classes.  These classes are offered in Toronto only.

  • Gem Appreciation – This is a 1-day, 5-hour general interest course designed to widen the knowledge of anyone interested in gems. It is particularly recommended for the consumer who wishes to make informed decisions when purchasing fine gemstones and gem-set jewellery, excluding diamonds.
  • Practical Gem Identification – This 10-hour, 2 day course, stresses the “how to” of gem identification and is the follow-up to Gem Appreciation. Learning basic instrumentation will show you how a gemmologist can distinguish between natural, synthetic and imitation gems found in modern and antique jewellery. Gem testing instruments are provided, but students should have their own pocket instruments (loupe, tweezers). We sell gemmological instruments.
  • Talking Diamonds – This 5-hour seminar cuts through the industry jargon and provides practical, easy-to-understand information about diamonds. It is intended for the first-time purchaser, or anyone interested in learning more about these fascinating gems.
  • Pearl Stringing – This 3-hour workshop provides hands-on experience in stringing pearls and beads, thus allowing you to make your own beautiful jewellery. There is a small additional cost for materials (silk thread, clasp) payable to the course instructor.
  • Individual lectures are also available on Tiaras, History of the Ring and a variety of other gemmology and jewellery topics.

Advanced Courses in Gemology

The CGA’s advanced courses are designed for trade professionals who have a professional gemmology diploma or are current gemmology students.  Pre-registration is required for these courses.

    • Sophisticated Synthetics and Gemstone Enhancements– Bring your knowledge of the important gemstones up to date! Emeralds, sapphires, rubies and diamonds are valuable gems for which many simulants and synthetic counterparts exist, and which are frequently enhanced.The primary focus of these workshops is on the nature and occurrence of inclusions within the various “sophisticated” synthetics, and the detection of new methods of enhancement. Participants will have a chance to practice the various techniques and tips provided for distinguishing naturals from synthetics and for detecting enhancements using gemmological equipment.
  • Coloured Gemstone Grading and Evaluation– This three-day workshop will benefit gem trade professionals, gemmology students and enthusiasts alike. Students will learn the skills to accurately grade and value coloured gemstones. Emphasis on hands-on practice with a variety of gems of different quality will provide students with the knowledge to become confident buyers and sellers in the rapidly growing coloured stone market.
