Abstract：Myanmar is the main commercial jadeite origin, Guatemala，Russia also have jadeite output. The value of jadeite from different origins varies greatly, and jadeite from other origins is impersonated as Burmese jadeite to get higher prices. Urgently need to be a reliable method to determine the geographic origin, the study of jadeite origin is of great significance in gemology. At present, jadeite from the different origins is mainly discussed in terms of jadeite generation age, mineral assemblage and jadeite component content, In this paper, jadeite from Myanmar, Russia and Guatemala is taken as the research object, lack of quick and effective ways to identify places of origins. The laser Raman spectroscopy of jadeite samples from different origins shows that the minerals of Jadeite from Myanmar are jadeite, chlorite and tremolite. The minerals of Guatemalan jadeite are relatively complex, including jadeite, omphacite，chlorite，titanite, uranite. The minerals of Russian jadeite are jadeite, albite and omphacite. By comparing the Raman characteristics of jadeite minerals from different origins, it is found that typical jadeite spectral characteristics show at 1 037，988，697，372 and 201 cm-1. At 1 020，679，369 and 216 cm-1，it shows the characteristic Raman displacement peaks of chlorite, and there are obvious tremolite absorption peaks at 215，332, 394，680 and 1 073 cm-1. tremolite is a secondary mineral in jadeite. Jadeite minerals from Guatemala are superimposed with Raman peaks of 680 and 218 cm-1，which is the peak value of the omphacite feature, and also contain the Raman peaks of chlorite feature near 603，537 and 306 cm-1. The results indicate that jadeite minerals from Guatemala are mostly replaced by Fe, Mg and Ca elements, forming jadeite-chlorite solid solution minerals. Raman spectral peaks of chlorite are detected on the surface of jadeite minerals, at 603，537 and 306，and chlorite alteration occurs on the surface of jadeite minerals. Russian Raman peaks of jadeite are superimposed with albitite Raman peak, at 1 100，507，473 and 164 cm-1 . Jadeite minerals in Russia are commonly metasomatized by albite Gray-green reticulated veins are distributed on the surface, and Raman peaks of 1 025，669，366 and 219 cm-1 are shown.
