From the Editor:
Since my return from a very successful AGTA GemFair in Tucson, Arizona we have been busy shipping orders and answering questions about our courses and products. I will be present at the C.I.G. booth during the BC Gem & Mineral Show (see below).
BC Gem & Mineral Show, Abbotsford – April 11, 12 & 13
Visit us at the Ag-Rec Building, Central Fraser Valley Fairgrounds, 32470 – Haida Drive, Abbotsford, British Columbia

Admission: Adults – $6.00, Students (6 – 17) – $2.00, Under 6 – Free
At the C.I.G. booth we have our full line of gem testing tools and several new titles of gem books on display; buy at the show and save on taxes and shipping costs.
We are also demonstrating the 2014 model of the GL Gem Raman PL532 TEC system and the GL Gem Spectrometer with an innovative attachment.
Please bring any gems or minerals for quick identification (even set in jewellery; max. 5 pieces per customer); we are particularly interested in jade, treated gemstones and diamonds of any kind (synthetic, coloured, HPHT, irradiated, etc).
Updated Webpages for Gemlab Research & Technology
Due to the increasing number of users around the world we have updated the GL R&T section of GEMOLOGY WORLD; you can reach it at www.gemlab.ws.

In the show room will be demonstrating the GL Gem Raman PL532 with new features to surpress fluorescence and share up-to-date information about detection of natural, synthetic, HPHT and CVD grown diamonds and their treatments. The use of the GL Gem Spectrometer will also be demonstrated.
GL Gem Spectrometer and GL Gem Raman Workshops
For present and interested future users of our advanced gem testing instruments we offer a 3-hour review and hands-on session on Tuesday, June 3 from 2:00 – 5:00 p.m.; the workshop is limited to 5 participants. Please contact us at gemlab@cigem.ca to reserve your space.
We also have an advanced 3 1/2 hour workshop scheduled for Tuesday, June 3, 2014 from 6:00 – 9:30 p.m.; please register on-line.
GEM 250 Gem Identification II (Advanced)
In this course students will learn state-of-the-art techniques (including emstone 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. Practising gemmologists may use this lab class to up-grade their skills.
- Prerequisite: “Gemmologist” certificate or similar gemmological qualification.
- Fee: $ 995 ($ 200 exam fee for A.G. Diploma not included); comprehensive study guide, Gemstone Inclusion Library, use of lab equipment and study stones.
- Date/Location: Sat – Tue, May 31 – June 3, 10:00 a.m. – 5:00 p.m., Sandman Signature Hotel – Vancouver Airport, Richmond B.C. (special room rate)
Day 1: Review of gem testing instruments; quick gem identification methods and practical work.
Day 2 and 3: Routine testing with microscope and selected gemmological tools to identify difficult gem materials loose and set in jewellery.
Day 4: Identification of challenging gem materials and their treatment; introduction to advanced identification techniques using the GLGemSpec and GL Gem Raman PL532 spectrometer.
Here a brief list of man-made gems in our study collection: Chatham, Kashan, Ramaura, Knischka, Lechleitner, Regency, Biron, Lenix, Gilson, Tairus rubies, sapphires, emeralds, alexandrite, opal, moissanite, CVD, synthetic diamonds and many others. Gem enhancement techniques such as heat-alteration, surface colour diffusion, irradiation, HPHT and glass filling are studied.
