Abstract Recently, attentions has been paid to the origin of high-quality turquoise. However, few researches of spectroscopic characteristics of them have been performed to differentiate its original location. Although the general characteristics of spectra are resembled for Qingu, Wenfeng (Hubei province) and Bijiashan (Anhui province) turquoises, minute difference can be observed among them. Infrared spectra of the studied samples in this investigation show that peak near 783 cm^-1 caused by OH bending vibration of turquoise from Qingu separates into two peaks, 797 and 779 cm^-1. While the peak appears at 787 cm^-1 for turquoises from Wenfeng and 783 cm^-1 for the ones from Bijiashan. Intensity ratios of infrared absorption peaks at 783 and 837 cm^-1(R=I_{783 cm^-1}/I_{837 cm^-1}) are different among them, more than 0.98 in samples from Qingu, 0.85 from Wenfeng and 0.93 from Bijianshan samples. Infrared band at 609 cm^-1, which is related to the ν₄(PO₄) stretching vibrations, is quite obvious and sharp of Wenfeng samples, appears wider and less sharp of Qingu samples, while for Bijiashan sample, is the most plane. Peaks in Raman spectra around 3 500 cm^-1 are different among the three locations, namely 3 506 and 3 505 cm^-1 for samples from Bijiashan, 3 495 to 3 500 cm^-1 for samples from Hubei province. Peak intensity around 3 472 cm^-1 of turquoise from Bijiashan is larger than those from Hubei with the same situation occurring at peak ~551 cm^-1. These findings, combining with appearance of the turquoises, can be used as important spectroscopic characteristics to recognize origins of the high-quality turquoises, which also have potential important implications in archaeology.
