【Abstract】 Treating atmosphere, heating rate, temperature, as well as annealing time are systematically tested in order to improve the gloss and the transparency of emerald, which is produced in Yunnan province. In terms of these studies, optimal treating condition is picked out and used in the following treating process to further enhance the gloss and the transparency of emerald through injecting or diffusing inorganic material into the cracks or holes in the emerald. Micro-zone Raman spectroscopy, ultraviolet-visible light absorption spectroscopy are employed to investigate the properties of treated emerald. The results demonstrate that the treated emerald is as good as expected, thus indicating that the treating processes employed are reasonable and effective.更多还原
