Application of Laser Raman Spectrometer on Non-destructive Analysis of Mineral Constituents and Mineral Contents in Jadeite and Related Jades

It is very significant to analyze the mineral constituents and mineral contents in Burma jadeite jade and related jades. Under high power magnification with reflected light, it can be seen that different minerals in jadeite jade and related jades differ in luster. Using Laser Raman spectrometer to measure the Raman spectra of different minerals with differrent kinds of luster, associated with statistical calculating of the square area percentage of different minerals, the mineral constituents and the mineral contents in jadeite jade and related jades can be estimated. Three examples of identification of omphacite jade, jadeite albite jade and jadeite edenite jade are given.
