| Abstract: | By the comparing study on ultrared spectrum of natural topaz and colour-changed topaz by irradiation, we found that the transmitted infrared spectra of the natural and colour-changed topazes are different. Based on the quantitative study on these differences, a mathematical model has been established to distinguish the natural topaz from colour-changed topaz. By combination with computer programming, the gem identification could become gradually automatic. |
