Research & Technology



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.

GL Gem Spectrometer

Our best-selling  GL Gem Spectrometer™  helps to identify gemstones based on their spectral pattern and to analyze chromophores causing certain colours. The integrated fast search spectral library of over 250 gem references covers common Gemstones, Diamonds (incl. treatments) and PL405 spectra.

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; it was introduced in 2010 and has been sold to users in 35 countries around the world.

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. It has been sold to users in 23 countries around the world

With the integrated fast search spectral library 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 even in their rough state.

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.
