摘　　要：近年来东陵石优化处理多为染色、漂白、充填等技术改变玉石的外观及物理性质。染料分为有机染料和无机染料,但由于有机染料多不稳定,不能达到很好的改色的效果,现在市面上多用无机染料对东陵石进行改色,能呈现较好的颜色,用来仿制高档玉石,染色的绿东陵有其独特的“丝瓜瓤”的颜色分布。浸蜡处理用来改变天然东陵石的透明度,可使宝石表面的小凹坑、孔隙填平,从而使宝石增强表面的光泽和透明度。除此之外,有的东陵石表面着有色蜡达到色泽鲜艳,改变其原本较弱的玻璃光泽,呈现强的玻璃光泽。利用常规的实验室仪器可以简单将其分辨,这种方法有着操作技术简单、测试环境要求不高的特点。In recent years, the optimal treatment of Dongling stone mainly involves dyeing, bleaching, filling and other techniques to change the appearance and physical properties of jade. Dyes are divided into organic dyes and inorganic dyes, but since organic dyes are unstable and cannot achieve good color change, inorganic dyes are now mostly used to change the color of the stone, which can give a better color and is used to imitate high-grade jade, and the dyed green stone has its unique “loofah” color distribution. The wax-impregnation treatment is used to change the transparency of natural Dongling stone, which can make the small pits and pores on the surface of the gem fill up, thus making the gem enhance the luster and transparency of the surface. In addition, some Dongling stone surface with colored wax to achieve bright color, change its originally weak glass luster, a strong glass luster. It can be easily distinguished by conventional laboratory instruments, this method has the characteristics of simple operation technology and low requirement of testing environment.
