摘　　要：水晶的颜色丰富,但致色机理各异。紫水晶主要是由Fe3++O-空穴心产生的;烟晶颜色主要依赖于Al3++O-空穴色心;黄水晶的颜色是在Fe3++O-空穴心与不带补偿离子的Al3++O-空穴心的联合作用下产生的。宝石的热处理工艺,是指在不同的加热氛围下对宝石进行加热,从而改善宝石的颜色的方法。对于水晶来说,紫水晶在经过加热后,紫色会先褪至无色再出现黄色调;烟晶的颜色会跟随着温度的提高而逐渐变浅,且颜色在室温下稳定;黄水晶颜色稳定,温度的改变并不会对其颜色带来变化;粉色水晶颜色基本不受温度的影响。Quartz is rich in color, but its coloration mechanism is different. Amethyst is mainly produced by Fe3++O-hole core;The smoky quartz color mainly depends on Al3++O-hole color center;The color of topaz is produced by the combined action of Fe3++O-hole center and Al3++O-hole center without compensation ion. The heat treatment process of gems refers to the method of heating gems in different heating atmosphere to improve the color of gems. In terms of quartz, after being heated, the purple of amethyst will fade to colorless and then appear yellow tone;The color of smokt quartz will gradually become lighter with the increase of temperature, and the color will be stable at room temperature;The color of topaz is stable, and the change of temperature will not change its color;The color of pink quartz is basically independent of temperature.
