This paper focuses on the application of external reflection Fourier Transform Infrared spectroscopy for the classification of some minerals commonly used as gemstones and mineral collection: quartz (colourless, tourmalinated and smoky varieties), calcite and aragonite. The results highlight the differences between reflectance and absorbance spectra, allowing a faster, cheaper and non-destructive approach for the identification of monocrystalline minerals.
