Dear Friends and Colleagues,
We have updated our website GEMOLOGY WORLD for both the Canadian Institute of Gemmology (C.I.G.) and Gemlab Research & Technology. Designed for optimal user experience, the new site provides exceptional accessibility on devices of any size. Its focus on simplicity and modern-feel creates a smooth transition to bridge the gap from traditional desktops to mobile devices.

We have made some changes to our Conditions of Sale and acceptance of credit cards. At the bottom of the page we have added a section “Delinquent Customers” to protect our customers from fraudulent buyers who may attempt to resell our products. Presently we have a dispute with Desjardins Card Services which used to be our merchant bank for credit card transactions.

Diamond Handbook (3rd edition, 2018) by Renee Newman
. |
The 3rd edition of the Diamond Handbook (2018) updates jewelry professionals and serious diamond buyers on new developments in diamond grading, treatments, synthetic diamonds, imitations and fancy-color diamonds. Using close-up photos, it shows how to make visual judgments about clarity, transparency, brilliance and cut quality. Basic and advanced methods of detecting diamond imitations, treatments and man-made diamonds are discussed and illustrated. Tables, charts, diagrams and more than 350 photos are included making this an excellent reference on natural, treated and CVD & HPHT diamonds. Highly recommended book order here.
Growing a Diamond Using CVD: Video

Here’s some lab-grown diamond news that does not involve De Beers. Created diamond company Altr has released a 2 minute, 14 second video that shows how it grows diamonds inside its facility in India.
Watch it here (from National Jeweler). |
The new GL Gem Spectrometer has a modern modular design and faster microprocessor. With the new GLGemSpec software (version 3.3) spectra can be saved and matched with the integrated fast search spectral library. 250 gem references cover Gemstones, Diamonds (incl. treatments) and PL405 spectra. There are now 300 GLGemSpec users in 35 countries around the world.
Perhaps now is the time to invest in a GL Gem Spectrometer; it is probably the most important low cost diamond testing tool as it is capable to detect the Cape lines (98% of natural diamonds are Type Ia), the GR-1 band of irradiated diamonds, the Si center often seen in CVD grown diamonds (in some cases without LN cooling), possible HPHT treatments, whether green jadeite is naturally coloured or spinel is synthetic or heat treated and much more.
SAVE US$ 2,000 and order DEMO GL Gem Raman PL535 TEC SOLD
This demo unit (2017 model) has been used during trade shows and product demonstrations; the unit has been completely upgraded with new motherboard (version 3.x) and is in perfect working condition (regular warranty). With the new GLGemRaman software (version 3.1) spectra can be saved and matched with the integrated spectral library of over 300 gem references or imported into a separate searchable database program with over 3,500 edited references; this database is linked to the large on-line mineralogical RRUFF database for Raman spectra. There are already GL Gem Raman users in over 23 countries.
