    真假水晶鉴别方法

    (1)眼看:天然水晶在形成过程中,往往受环境影响总含有一些杂质,对着太阳观察时,可以看到淡淡的均匀细小的横纹或柳絮状物质。而假水晶多采用残次的水晶渣、玻璃渣熔炼,经过磨光加工、着色仿造而成,没有均匀的条纹、柳絮状物质。

    (2)舌舔:即使在炎热夏季的三伏天,用舌头舔天然水晶表面,也有冷而凉爽的感觉。假的水晶,则无凉爽的感觉。

    (3)光照:天然水晶竖放在太阳光下,无论从哪个角度看它,都能放出美丽的光彩。假水晶则不能。

    (4)硬度:天然水晶硬度大,用碎石在饰品上轻轻划一下,不会留痕迹;若留有条痕,则是假水晶。

    (5)用偏光镜检查:在偏光镜下转动360度有四明四暗变化的是天然水晶,没有变化的是假水晶。

    (6)用二色检查:天然紫水晶有二色性,假水晶没有二色性。

    (7)用放大镜检查:用十倍放大镜在透射光下检查,能找到气泡的基本上可以定为假水晶。

    (8)用头发丝检查:将水晶放在一根头发丝上,人眼透过水晶能看到头发丝双影的,则为天然水晶,主要是因为水晶具有双折射。

    (9)用热导仪检测:将热导仪调节到绿色4格测试宝石,天然水晶能上升至黄色2格,而假水晶不上升,当面积大时上升至黄色一格。
