Abstract
The green tourmalines from Kayah state, Myanmar were investigated by WD X-ray fluorescence, UV-vis, and mid-infrared spectroscopy for comparison to tourmalines of other deposits. The group of tourmaline was calculated and classified by chemical analysis. The samples belonged to the Calcic group and Uvite. The green tourmalines showed a strong absorption band at 415 and 611 nm. The presence of $V^{3+}$ ions is responsible for these absorption bands. Combination of the stretching and bending mode by the vibration between cationic and hydroxyl units (metal-OH) are observed in the 4600 ~ 4200 $cm^{-1}$.
