Abstract
The article provides a brief review of applying the infrared spectroscopy method to study of jewelry stones. The authors demonstrate the advantages of the frustrated total internal reflection (FTIR) method in gemological examinations. They also address the possibility of recording infrared spectra of faceted gemstones by the frustrated total internal reflection method on the infrared-Fourier spectrometer Nicolet iS5. The infrared spectra of some jewelry stones (diamond, moissanite, topaz, aquamarine, amber, pearls) are presented. The possibility of identifying and differentiation of jewelry stones from their synthetic imitations is considered as well.
