This is the upgraded 2017/18 model with new motherboard and “Point & Shoot” software. Now with integrated fast search spectral library of over 250 gem references covering common Gemstones, Diamonds (incl. treatments) and PL405 spectra.

The GL Gem SpectrometerTM system (300 - 1,000 nm) is an innovative tool for gem dealers , mineral collectors, gemmologist appraisers and geoscience applications. It replaces the traditional hand-held spectroscope avoiding potential eye damage under strong halogen light.

It helps to identify gemstones based on their spectral pattern and to analyze chromophores causing certain colours. 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.

The unique gem holder (VIS-NIR,  optimized for 400 - 950 nm) is mounted directly onto the spectrometer allowing fast real-time spectral analysis and bulk testing of both rough and faceted gemstones. For work with darker gems and diamonds,  larger samples and/or gems set in jewellery we recommend the GL Xenon Flashlight setup. 

For photo-luminescence studies (PL spectroscopy) we recommend the GL Analyzer PL405 Kit which provides a blue laser (405 nm) and necessary accessories.

Compact size: 170 mm x 100 mm x 50 mm - Weight: 510 grams

PLEASE NOTE: Using a fiber probe with the GL Gem Spectrometer requires a customized setup with external lighting and will change several parameters for obtaining a spectrum. Results may vary dependent on light source and its position, sample size (affecting path length) and orientation, etc.; spectra will look different from those found in the database and/or obtained with the GL 10W Halogen Gem Holder.

Our Warranty and Commitment

The GL Gem Spectrometer is an advanced gem testing instrument for users who have a good understanding of spectroscopy and should be familiar with the use of a traditional gemmological spectroscope and the interpretation of spectra. The instrument is not capable of identifying or naming a sample; it should be used with other gem testing tools before arriving at a conclusion.

If you are not satisfied with the performance of the spectrometer we will accept returns within 10 days but have to charge a restocking fee of 10% 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 will repair and replace your GL Gem Spectrometer if necessary due to defective parts, etc during the first 6 months unless other consumer protection regulations exist in your country. We also offer firmware/CCD upgrades for a processing fee of US$ 530 which covers the update, new software, re-alignment and re-calibration, etc. and return shipping charges; other repair services upon request. Software updates are always free.
