Spectroscopy has been long used in the gemology industry for characterization and identification, with nearly every known spectroscopic method playing a critical role. Transmission provides insight into gemstone clarity, reflectance provides colorimetric data, fluorescence & absorption are excellent at detecting bulk defects, and Raman & Laser-Induced Breakdown Spectroscopy (LIBS) provides molecular and atomic composition.

In this application note we show how easy it is to perform spectral analysis of garnets by comparing spessartine garnets from different geographic regions, using three spectroscopic methods.
