Education Workshops by GRI and CGL-GRS
All original research findings are utilized to develop educational lectures, programs and workshops, on a variety of gemological topics. Education programs have been presented in 17 countries on 4 continents.
Consulting & Research by Gemmological Research Industries Inc.
Consulting/Research projects on Rough diamonds, Fluorescence of Diamonds, Origin of color of natural diamonds, Treatments of Natural and Synthetic diamonds and Instrumentation.
Co-Organizing annual Mediterranean Gem and Jewellery Conferences
Lectures and workshops from leading Gemmologists, Dealers, and Experts on a broad range of subjects but crucial topics that are most worrisome to Jewellers, Gem Dealers and Appraisers.
The mission of the Mediterranean Gem and Jewellery Conference is to educate and help people understand the properties of diamonds, gems and jewellery in the creation of a sustainable business.
Identification & Grading of Diamonds by CGL-GRS Lab
Head Gemmologist Branko Deljanin is a world known specialist in identifying, grading and determining the colour origin (natural, treated, or synthetic) of diamonds using standard and advanced instruments.
CGL-GRS Lab was founded in the summer of 2009 by B. Deljanin and W. Vermeulen in Vancouver. This is the most technologically advanced Gemological Laboratory in Canada.
Testing & Identification of Gems, Jades, and Pearls by CGL-GRS Lab
Use of non-destructive advanced techniques like X-ray imaging, spectroscopic, and chemical analysis helps to distinguish all gem material and disclose treatments and country of origins on major gemstones.
Jewellery & Appraising Reports by CGL-GRS Lab
The results will be documented in a Jewellery Report that will disclose discovered treatments / synthetics. When a value is requested then an appraiser will give an estimated replacement value.
Grading & Provenance Reports on Coloured Diamonds with GRS Lab Hong Kong
In 2013 CGL-GRS joined forces with GRS lab (A. Peretti) to establish 5 research centers in Switzerland, Hong Kong, Thailand, USA and Canada and create worldwide service on grading of coloured diamonds.
Development of Standard Gemmological Instruments and creating Books
Use of Synthetic Diamond Identification Kit to screen and separate synthetic, treated and natural diamonds using LW and SW fluorescence and characteristic pattern under CPF using original handbooks Fluorescence as a Tool for Diamond Origin Identification and Identifying Diamond Types and Synthetic Diamonds with CPF (Cross Polarized Filters).
