Infrared spectrometer, Raman spectrometer, EPMA, and X-ray powder diffractometer are very effective equipments for the identification of jadeite. Some kinds of raw jadeite fakes occurred in the identification and jewelry market recently. With the methods of infrared spectrometer, Raman spectrophotometer, EPMA, and X-ray powder diffractometer etc., these typical fakes have been systematically studied. These fakes have superficial resemblances such as texture, outer characters and color of minerals in rocks. The relevant information of these fakes has been obtained. Meanwhile, several kinds of rough materials with fake weathering crust and cutting groove were analyzed. These identification methods were compared with each other. Type-B can be tested by infrared spectrometer, Raman spectrophotometer, and X-ray powder diffractometer. The present paper means a lot for the identification, evaluation and business of jadeite.
