A Review of Richard D. Armstrong’s Photoatlas of Gemstone Spectra for Gemology Students
/
Obtaining a spectrum on a gemstone is one of the most difficult skills to master in gem identification. Richard D. Armstrong’s Photoatlas of Gemstone Spectra for Gemology Students ($14.95 excluding shipping) seeks to aid students of gemology and gemologists in this endeavour.
The photoatlas is conveniently contained on a disc made for PC computers. The photoatlas provides the user with spectra for various stones as well as tips and techniques for using spectroscopes. Armstrong has marketed the photoatlas specifically for PC use, though files for both Mac and mobile platform are also contained on the disc if the user would like to attempt to use them. The program did not autorun on my Windows 8 PC; I had to open it manually. Once open, the the format of the photoatlas is a PDF virtual book that is very user friendly.
There are some challenges that students and gemologists continually face with spectra. Firstly, the lab manuals only contain drawings of the absolute perfect spectra, which are rarely (I would cautiously say never) what an individual sees. Secondly, the spectroscopes available in a campus classroom setting are usually perfectly mounted scopes with a perfect lighting setup. Many students will never again work with, let alone be able to afford, such a setup. They leave the classroom with no real concept of how to use any other style of instrument. Lastly, there is an increasing number of distance education students who will not have the same hands-on opportunities as on-campus students. This disc helps fill these voids and gives valuable confidence to the student as well as the seasoned gemologist.
