Six natural tourmaline crystals with different colors were investigated
by near-infrared (NIR) absorption specfroscopy. The tourmaline crystals
were obtained from Lucyen mines in Vietnam. The NIR absorption spectra
were recorded in two ranges of 4000-5000 crn' and 6500- 8000 crnt. We
found, according to their NIR spectra features, these six tourmaline
crystals can be classified into four groups: Gl, liddicoatite; G2,
elbaite; G3, dravite; and G4, Uvite. This grouping is consistent with
the chemical composition analyses and our earlier Raman studies.
