While GemmoRaman-532™ is excellent tool for identifying gemology related materials it would be unethical to market it as black magical box without limitations. Of course it does have them. Every analytical instrument ever made has applications where it shines like a star and then some other fields it simply doesn't work.
First of all, we would like to point out this is relatively low cost product for being Raman spectrometer. It is very good for general identification purposes but it should not be directly compared to high end research grade Ramans having ten or twenty times higher figures on their price tag.
Expensive Raman units are never developed for gemological use since big names are not interested to a niche market. At the same time, every expensive Raman unit is almost never developed having a particular field of work in mind, it must be designed to be used for a wide number of applications: organic and inorganic chemistry, quality control, pharmaceutical, metallurgy, environment sciences etc. Basically a big name manufacturer almost never produces a machine for a single use only. This is one of the reasons why Raman units are often very expensive. The typical user does not take 100% advantage of it’s potential, especially from the library point of view. GemmoRaman-532™ and it's software are specifically designed for gemology. GemmoRaman-532™ library spectra were compared to results obtained with a research grade first class confocal MicroRaman table unit, they matched perfectly for gemological use.
