Dear C.I.G. students and friends,
Just a reminder of the following upcoming events. I hope to see many of you during the first annual Vancouver Gem Show, August 14 – 16.
Please register for the fall C.I.G. Professional Development Courses soon as the number of participants is limited (see GEM 250 Advanced Gem Identification below).
IMPORTANT: Again I urge all Gem-A members to cast their vote in the upcoming election for Trustees. The choice is between a trade association headed by “Seven Disgruntled Members” (also read ISG Editorial) or candidates who will support the high educational standards of Gem-A and are qualified to run a modern UK professional association. Only one candidate is a Gem-A diploma holder; Ronnie Bauer FGA has never written a Gem-A examination!

GEM 210 DIAMOND GRADING
This course is an up-date course for A.G. (C.I.G.) diploma holders and graduates of other schools and institutes.
- Course Type: Combination of correspondence course and weekend/during week (2 1/2 days) workshop. C.I.G. DIAMOND GRADING certificate
- Prerequisite: A.G. (C.I.G.) diploma or equivalent (please contact us)
- Fee: $ 995 includes home study lessons (must be completed prior to workshop), grading projects with actual diamonds, study materials and exam fee (no HST) but does not include the textbook “Diamond Grading ABC: Handbook of Diamond Grading” by Pagel Theisen, 2007 (price $ 90)
In ten (10) assignments you learn the basic knowledge to buy, sell and evaluate diamonds effectively.
In five (5) practical sessions you grade diamonds for clarity, colour and cut (according to GIA and European (CIBJO) grading standards) including performance and device based approaches such as AGS (American Gem Society) ASET, Hearts & Arrows (Ideal Scope), Cut Advisor and others. Special procedures for assessing the quality of mounted diamonds will be shown.
Course Content: 1. Introduction to Diamond Grading 2. Determination of Colour Grades 3. Clarity Nomenclature and Grading 4. Cut and Proportions 5. Evaluation of Colour, Clarity and Cut 6. Diamond Grading Procedure 7. Representation of external and internal features 8. Practical Grading of Clarity, Colour and Cut 9.Proportionscope and Fancy Cuts 10. Grading Tools, Recutting, Diamond Imitations, HPHT Treatments, Synthetic Diamonds

GEM 250 Advanced Gem Identification
The following course is an up-date course for A.G. (C.I.G.) diploma holders and graduates of other schools and institutes; it is recommended as an introduction to the use of advanced gem testing equipment.
In this advanced course students will learn state-of-the-art techniques (including immersion-scope, gemstone magnetism, IR-VIS-NIR and Raman spectroscopy), etc. designed to identify confidently any gemstone encountered in the market place. Between 100 and 120 challenging gems including the most recent synthetics and treatments are available for testing. Max 5 participants.
- Fee: $ 995 includes comprehensive study guide and materials (copy of Gemstone Inclusion Library), use of lab equipment and study stones. Recommended text-book: Gemology by Peter Read. Download course flyer (PDF).
