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.
  • NEW – Diamond and Diamond Imitations – This 2-day (12 hour) course teaches the students to identify diamonds and diamond simulants. It is intended for the student planning to take a diamond grading course or anyone interested in diamond simulants. Can you identify a CZ, natural zircon, synthetic moissanite, YAG, GGG, synthetic rutile, strontium titanate and more?
  • 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 Stone Grading and Valuation– 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.

This an intensive, hands-on course which will provide knowledge and skill in the grading of colourless, round brilliant cut diamonds. Please note: this course focuses on the diamond grading process, not the identification of diamond and/or its simulants. All necessary major equipment is provided, but students should bring their own pocket instruments (which are available at reasonable cost on-site). Required course textbook may be purchased separately. Class size is limited to a maximum of 8 students.

No Prerequisites: If you do not have industry experience then we recommend that you attend a one day Talking Diamonds class. If you are unable to differentiate between a diamond and its imitations (CZ, synthetic moissanite, synthetic rutile, zircon, strontium titanate…) then we recommend that you take our new two day class called Diamond and Diamond Imitations.

Gemmologist, Jeweller, Appraiser – What is the difference?

When I introduce myself to people as a gemmologist, I am often asked if I have made my earrings.  This is very frustrating because it confirms my suspicions that people don’t know what a gemmologist does!

When you walk into a jewellery store who will you meet?  Will it be a jeweller, a gemmologist or a jewellery appraiser?  What services can each of them provide?  Who do you need?

Emerald – The Most Valuable Member of the Beryl Family

At one time all green gemstones were refered to as emeralds.  When we were able to determine that not all green stones were emeralds, we also discovered that some of the Egyptian Queen Cleopatra’s Emeralds were infact another less expensive green gemstone called Peridot.
