This demo unit (2016/2017 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).

GL Gem Raman PL532TM is an advanced gem testing instrument for gem technologists, experienced jewellery appraisers, gem dealers, mineral collectors, researchers in geoscience applications and laboratory personnel; it is also an excellent educational tool.

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, gem materials set in jewellery and rough minerals (no preparation necessary).  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 can identify 0ver 3,500 minerals.

The detection of the SiV optical center at 737 nm is commonly seen in CVD grown synthetic diamonds but appears to be unstable. Taidiam IIa company and  Apollo/SCIO may show 737 nm line (including very few natural diamonds), Element 6, Washington and Taidiam (after immersion in Liquid Nitrogen) diamonds have NO 737 nm peak.

Package Includes

  • The package comes with a support CD (including video) for proper operation of the GL Gem Raman;  a trained gemmologist or mineralogist should be able to follow and execute the step-by-step instructions including the calibration procedure (built into software version 3.x) if necessary.
  • GLGemRaman operating software and support materials (including videos) on CD and USB stick (for portability) with single user license. The 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.
  • Detailed "How to get started" instructions and access to C.I.G. (Canadian Institute of Gemmology) spectral database of gem study collection.  Skype video-conferencing for assistance is also available.

There are already GL Gem Raman users in over 22 countries including Belgium, Brazil, Canada, Czech Republic, Cyprus, France, Germany, Hong Kong, Indonesia, Israel, Kuwait, The Netherlands, Oman, Singapore, Slovakia, Sri Lanka, Taiwan, Thailand, UK, USA, Vanuatu and Vietnam.

The GL Gem Raman PL532 TEC is being used for scientific research in the Department of Earth and Environmental Sciences at the University of St Andrews, Scotland and at The Mineral Technology Center (CETEM) – a research institute of the Ministry of Science, Technology and Innovation (MCTI) in Rio de Janeiro, Brazil.

Dank des vollständigen Zubehör-Sets konnten wir sofort starten - das war eine große Erleichterung. Die Inbetriebnahme war ein Kinderspiel und die erzielten Spektren sind aussagekräftig. Nun haben wir schon zahlreiche Messungen gemacht und wir sind sehr zufrieden (!) mit den Ergebnissen. Die Edelstein-Identifizierung ist absolut kein Problem und wird im EPI-Labor sicher eine Standardprozedur für alle Fälle, bei denen auch nur der leiseste Zweifel an der Identität auftritt. Es ist ideal, um winzige Steine in der Fassung zu identifizieren. So wie es aussieht, können wir dank der Unterstützung des GL Gem Raman und der mitgelieferten Datenbanken zukünftig auf aufwändige EDX-Analysen verzichten. Das verkürzt den Arbeitsablauf erheblich.- Bernhard Bruder, Dipl.-Mineraloge, EPI - Institut für Edelsteinprüfung, Ohlsbach, Germany As all required accessories were included we could start immediately - that was a big relief. Start-up was a breeze and the spectra obtained were convincing. We have already made numerous measurements and we are very satisfied (!) with the results. Gem identification is no problem and in the EPI laboratory it certainly will become a standard procedure for all cases in which even the slightest doubt about the identity exists. It is ideal for tiny stones set in a piece of jewellery. Thanks to the support materials for the GL Gem Raman and the supplied databases we can avoid expensive EDX tests in the future. This will shorten the workflow significantly.- Bernhard Bruder, Dipl.-Mineraloge, EPI - Institut für Edelsteinprüfung, Ohlsbach, Germany

Our Warranty and Commitment

The GL Gem Raman is an advanced gem testing instrument for experienced users;  a match in the reference data-base is not a 100% guarantee that the sample has been properly identified. The instrument  should be used with other testing tools before arriving at a conclusion. If you are not satisfied with the performance of the Raman spectrometer we will accept returns within 21 days but have to charge a restocking fee of  5% to cover our expenses of shipping/handling and recalibration if necessary. The purchaser is also responsible for the shipping and insurance to return the item.

We package the Raman unit very carefully but cannot assume any liability as soon as the unit is out of our hands. If the package shows signs of damage or  the GL Gem Raman appears inoperable please contact us and file an insurance claim with the shipper immediately. If it is a serious calibration problem which cannot be fixed by the user we have a procedure in place which should be conducted by an experienced technician; these specialists usually service university and medical laser equipment. The purchaser is responsible to contact this person; presently we have support staff in Germany, Canada and the USA.

IMPORTANT: We do not recommend to transport the Raman unit in checked luggage for air travel unless the unit is well protected; as a carry-on item IT MAY NOT BE ALLOWED past most airport security checks due to the class B3 laser in the case.

We will repair and replace your GL Gem Raman if necessary due to defective parts (not as a consequence of physical and/or thermal shock while in a vehicle, boat or an aircraft), etc during the first 12 months (no warranty for laser in this upgraded 2015 model) unless other consumer protection regulations exist in your country. The customer is responsible for return shipping and insurance to Vancouver, Canada.

For maintenance services a processing fee of US$ 995 (price may change) will be charged which covers any firmware update, re-alignment and re-calibration, etc. and  shipping charges; other repair services upon request. The Raman unit should be operated in a dust-free environment. Software updates are always free.

The GL Gem Raman™ PL532 TEC and the GL Gem Raman Band Pass Filter™ (GLBPF) is an exclusive design by Gemlab Research & Technology (a subsidiary of Canadian Institute of Gemmology) and its software is protected by copyright laws; we are the exclusive distributors worldwide.
