CIGem News Fall 2016

Dear Friends and Colleagues,

after attending  Facets 2016 in Sri Lanka and spending some time in the Austrian Alps I am back  preparing for our fall activities. I am looking forward to the upcoming workshop and welcome our foreign participants.

I want to thank Gamini Zoysa who hosted an Advanced Spectrometry Workshop in Colombo after the gem show; we had attendees from several countries who could familiarize themselves first hand with the operation of  the GL Gem Spectrometer  and the GL Gem Raman PL535.

Also start planning for the AGTA GemFair in Tucson from Jan 31 – Feb 5.

Please note in your calendar the following dates:

Visit to the Gem Mining Areas in Rathnapura, Sri Lanka

I visited several several small scale sapphire mines nearby with Kasun (Hotel Gem Land).

More images and report at the Facebook page of the Canadian Institute of Gemmology.

Highly Recommended New Book

Gem Guide

I just received this exceptional new book (almost coffee table size). Each of the 440 pages is full of images and in-depth descriptions of gems and jewellery; I liked in particular the section on emerald and opal.

It can be purchased for US$ 35 or less at Amazon or Target.

GL Gem Spectrometer 2016/17 model

We have replaced the motherboard in the GL Gem Spectrometer with a modern modular design and faster microprocessor. This will allow us to add new features and components in the future such as Bluetooth, WiFi communication, database search, etc. With the new GLGemSpec software (version 3.2)  spectra can be saved and matched with the integrated spectral library of over 180 gem references (experimental).

The 2016/2017 model of the GL Gem Spectrometer is now available.

Watch how a normalized absorption spectrum of green glass is obtained in 25 seconds (video, no sound).

GL Gem Raman PL535 2016/17 model

Our Raman spectrometer comes with a new motherboard, “Point & Shoot” software and integrated spectral library; fast averaging allows real-time observation of the Raman spectrum. All units come now with a mechanical laser security lock.

Databases have been updated and are available for download in the GLGemRaman Support section With the new GLGemRaman software (version 3.2) 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.

FOR SALE

One GL GemRaman PL532 TEC Demo unit in excellent condition.

CIGem News Summer 2016

Dear Friends and Colleagues,

We had many visitors to our booth during the Vancouver Gem & Mineral Show last week-end; I am now preparing for a trip to Europe and Sri Lanka. Please note that  there are limited Office Hours from August 23 – September 19.

If you are interested in participating in an advanced spectroscopy workshop (“Raman and PL Spectroscopy in Gem & Mineral Identification” with hands-on exercises) on September 7  – a few days after FACETS Sri Lanka, Colombo (September 1 – 4) – contact Gamini Zoysa at gaminigz@hotmail.com for further information.

Enjoy the rest of your summer holiday season.

A new educational CD about spectroscopy

A Guide to the Spectroscope

John Harris has published a Guide to the Spectroscope (PowerPoint presentation).

It is a valuable educational tool for beginners as well as experienced spectroscopists.

Instructors will love the format as the guide can easily be projected in a classroom situation or during a workshop. 

.

Also have a look at his “Through my Spectroscope” column which now includes  his own GL Gem Spectrometer.

New version of Spekwin32

Dr. Menges has published the final version of Spekwin 32 (1.72.2, June 15); it is a comprehensive software for editing and publishing spectra and allows direct import of GLGemSpec files (.fak) and GLGemRaman files (.rruff). He has started work on the all-new Spekwin32 successor to be released later this year.

Of particular interest is the Spectroscope View for owners of the GL Gem Spectrometer. Download the guide “Show Spectroscope View”

Also look at his universal software for DIY webcam spectrometers.

News from Gemlab R&T

Users of the new software version 3.00 of both the GL Gem Spectrometer and the GL Gem Raman PL535 2016/17 models should soon receive a small update.

The spectrometer software will have an “auto-y scale” icon (like in the Raman software by default) which keeps the spectrum visible at all times; this is possible to the new electronics built into the model 2016/17 spectrometers. As the spectrum is delivered in real-time adjustments to exposure, etc are seen immediately.

For the Raman software the search function will be unlocked and the provided data-bases can be accessed directly; user spectra can then then be easily added.

FOR SALE

GL GemRaman PL532 TEC Demo (2015 model refurbished)

Meiji GEMZ-8TR microscope  in almost new condition.

We also have 2 used Kyowa microscope setups (20x, 40x, made in Japan) and 2 used Kyowa refractometer units (made in Japan) for sale. For sale: 1 calcite dichroscope, 1 grating diffraction and 1 prism spectroscope with halogen light source and several other testing instruments.

GL Gem Spectrometer 2016/17 model

If you have an iPhone or similar cellphone you know that a new model with better electronics and features will be offered by the manufacturer every year. Some people replace their phone regularly others are happy if there are any upgrades for their old models. 

After five years and a user base of over 200  around the world we decided to replace the motherboard in the GL Gem Spectrometer with a modern modular design and faster microprocessor. This will allow us to add new features and components in the future such as Bluetooth, WiFi communication, database search, etc.

The new software version 3.0 does not run on previous models and provides a simple interface that produces a stable normalized transmission/absorption spectrum in real-time. The screen can be saved and printed out in addition to fast loading of reference spectra, etc.

Watch how a normalized absorption spectrum of green glass is obtained in 25 seconds (video, no sound).

For users of the older spectrometers we upgraded the software to version 2.8;  an upgrade package is available for download in the GLGemSpec Support section. To access the user section you have to log-in; if you lost your password please request a new one and the system will send it to your e-mail address.

Jade & Abalone Pearl Handbook

Exotic Gems, Volume 4 (Can$ 29.95) by Renee Newman will be available during the BC Gem Show, Abbotsford BC.

Exotic Gems

Buying jade is a challenge because its value can vary significantly depending on its quality and treatment status. Moreover, fake jade is prevalent in the marketplace.

Exotic Gems, Volume 4 describes with text and photos how to evaluate jade quality, as well as detect imitations and dyed jade. The guide also illustrates advanced detection techniques, and compares price factors and characteristics of jadeite and nephrite jade.

Abalone pearls are also covered, with tips on how to identify and evaluate them.
