【导语】在日常接待顾客的过程中，很多顾客对于钻石的荧光不是很了解，所以今天本地宝的小编在此为各网友解说一下钻石的荧光反应，让大家更了解钻石的荧光反应是什么。 买钻石的三误区——产地,透明度,金属衬托南非鉴定师 教您巧妙挑选钻石颜色教你如何挑选最好净度的钻石 一、钻石的荧光是什么? 荧光(Fluorescence)指标是指钻石在强烈紫外线下会发出的蓝光或者黄光等有色光的强度。简单来说，就是在自然光线下，或者室内光线下是感觉不到钻石的荧光的，除非在紫外线比较强烈的夏天阳光下，具有很强荧光性的钻石，可以用肉眼感觉到荧光的存在。即使如此，钻石荧光对您的日常佩戴也没有任何影响。 二、天然的钻石都有荧光吗? 并非所有的钻石都具有荧光，但是确实是存在有一定比例的钻石是具有荧光效应的，国际上检测钻石一般是要将荧光指标标注出来的。 三、荧光的颜色和强弱怎么区分? 钻石的荧光并非都是蓝色，钻石的荧光有蓝色、黄色、橙黄色、粉色等等。钻石的荧光有强有弱，GIA划分的荧光级别由低到高分别是NONE(无)、 FAINT(微弱)、 MEDIUM BLUE(中等)、STRONG(强)。钻石的荧光在GIA证书上都有说明，您不必担心自己去分辨。 四、钻石的荧光影响钻石的价值吗? 荧光虽然是个天然指标，无或弱荧光钻石对钻石价格没有影响，但中等以上荧光的钻石在国际价格里会有3%--5%的差距。钻石的价值主要取决于其4C，也就是颜色、净度、大小和切工。其它指标只是作为辅助参考。世界上著名的蓝色钻石——希望之星(Hope)就是一颗具有强荧光的钻石。 五、钻石荧光有没有辐射，对健康有影响吗? 钻之源告诉您，荧光反应和辐射完全是两回事。天然钻石的荧光反应不是辐射引起的。荧光反应的原理是钻石在紫外光线照射下，由于含有氮原子杂质，紫外能量被它吸收以后立刻在较低能级或者以较长波长重新发射的现象。我们所能看到的荧光钻石蓝色荧光，是不具有放射性的。因而对健康不会有任何影响，您完全可以放心。 六、有无荧光的钻石看起来有区别吗? 一颗有蓝色荧光的钻石在有紫外光的光源照射下会比没有荧光的钻石同等色级下显得更加白一些，出火时蓝色的光芒会更多一点，但是这取决于钻石的大小和荧光强弱。GIA证书在检查钻石颜色时，是在不含紫外光的标准光源下观察的，所以对颜色的判定不受荧光反应的影响。两颗相同色级的钻石在含有较强紫外光的阳光下观察时，带蓝色荧光的钻石很有可能会比不带荧光的钻石更白些。
