Using conventional gemological methods, energy dispersive X-ray fluorescence spectrometer, laser Raman spectrometer, Fourier transform infrared spectrometer and fluorescence spectrometer to compare the spectral characteristics of natural and filled amazonite and to explore the effective and non-destructive identification method of filled amazonite. The results showed that the refractive index of filled amazonite is consistent with that of natural amazonite, which is 1.52~1.53. The luster of filledamazonite is weaker glass to wax, which is weaker than natural amazonite. Enlarged observation shows that the surface is concave in the partially filled amazonite samples, and the luster is different from the surrounding. There may be bubbles in the cracks. So the weak luster and magnified observation can help distinguish natural amazonite from filled amazonite. The main elements are the same either in nature or in filled amazonite, including Al, Si, K and Rb. No abnormal chemical elements belonging to the filling material have been detected. The infrared reflection spectrum in the fingerprint area is the absorption of the group vibration of amazonite. In the functional group area, natural amazonite does not absorb obviously, while the filled amazonite has two characteristic absorption peaks that 2 844 and 2 912 cm^-1, produced by the vibration of (—CH₂—). The laser Raman spectra of natural and filled amazonite are the same in the 100~1 500 cm^-1 band, which are all the Raman peaks produced by the group vibration of amazonite. The fluorescence background of filled amazonite in the 100~3 700 cm^-1 band is stronger than natural amazonite. When organic filling material in surface fissures is detected, the fluorescence background will be stronger, and the Raman peaks will appear different from natural amazonite. There is no typical difference between natural and filled amazonite, and natural amazonite different fluorescence characteristics by themselves. The three-dimensional fluorescence spectrum cannot distinguish natural amazonite from filled amazonite.
