Three groups of nephrite of different colors at special temperature were heat-treated, and good forged effects of archaic jades were obtained. Then their Raman spectra were tested. The results of the tests showed that the Ramen spectra for the forgeries were significantly different from those for unheated nephrite. In the Raman spectra for the forgeries, the three of four Raman peaks between 252cm-1 and 395cm-1 were changed into two peaks between 324cm-1 and 327cm-1 and the other was between 389cm-1 and 395cm-1. The peaks between 666cm-1 and 668cm-1 and between 1019cm-1 and 1027cm-1 were shown in a little lower shifts between 662~665cm-1 and 107~1010cm-1 respectively. The peak between 510cm-1 and 526cm-1 was changed obtusely. The peak at 926cm-1 almost disappeared. And the peak between 1304cm-1 and 1310cm-1 was observed only in those Raman spectra for the forgeries, which resulted from heat-treatment.
