FTIR spectroscopy in jewelry analysis

Fourier Transform Infrared Spectroscopy (FTIR) is a popular technique in the jewelry world for classifying diamonds, as well as a useful tool for determining artificial diamonds. Natural diamonds are characterized by various inclusions, for example, isolated nitrogen atoms or clusters, the absorption bands of which occur in 1 300 – 1 000 cm-1 range. Such defects are characteristic of natural stones and are not found in artificial ones.
