Gemlab Research & Technology (GLR&T) is part of Gemlab Group and a subsidiary of the Canadian Institute of Gemmology (C.I.G.); the facility has developed advanced gem and mineral testing instruments such as the GL Gem Spectrometer™ and the GL Gem Raman™ PL532 TEC.
Official Sponsor of 11th GeoRaman Conference, St. Louis, MO, USA June 15 – 19, 2014.
Official Sponsor 4th International Gem and Jewelry Conference, Chiang Mai, Thailand Dec. 8 – 9, 2014
GL Gem Spectrometer
The popular GL Gem Spectrometer™ helps to identify gemstones based on their spectral pattern and to detect chromophores causing certain colours.
It is also useful to detect irradiated diamonds and possible HPHT treatments and whether green jadeite is naturally coloured.
It is a portable unit connected to a computer and replaces the traditional hand-held spectroscope avoiding potential eye damage under strong halogen light.
GL Gem Raman PL532
The GL Gem Raman™ PL532 TEC is an advanced dual purpose gem testing system for experienced gemmologists, gem dealers, mineral collectors, researchers in geoscience applications and laboratory personnel; it is also an excellent educational tool. It was introduced in 2012 and is the first and fastest commercially available Raman and Photoluminescence (PL) spectrometer offered at an economical price.
The GL Gem Raman quickly can tell the difference between diamond, cubic zirconia, glass and zircon, distinguish natural from polymer treated jadeite and from nephrite, separate real from faux pearls, tell whether it is ivory or plastic; it works great on beads, carvings and gem materials set in jewellery.
It is very efficient in detecting treatments such as irradiation, HPHT and other colour enhancements in gemstones; it will help in the determination of the nature of diamonds, gemstones and minerals.
NEW: GL Gem Raman Band Pass Filter (GLBPF) for suppression of fluorescence in Raman mode
Gemlab Research & Technology (GLR&T) conducts independent research in gemmology and mineralogy related areas.
Early projects included colour gem grading with spectrometers and gem identification techniques using an immersion-scope. More recently portable fibre-optics spectrometers and innovative lighting technologies have expanded traditional gem testing procedures; they will become important tools for the practising gemmologist in the future.
As a subsidiary of the Canadian Institute of Gemmology GLR&T is in the forefront of providing professional development to its graduate students and members of the jewellery trade.
