综上所述，钻石晶体中的致色元素及各种色心在长波紫外线的照射下会使电子从基态跃迁至激发态，然后自动返回到基态，这个过程中会释放出能量，并发出可见光，即我们所看到的荧光效果。

为什么钻石荧光强度有所有不同？

A色心是钻石荧光的抑制剂。天然钻石中常含有由两个氮元素组成的A色心，经研究发现A色心会抑制钻石荧光的出现。因此天然钻石的荧光强度与其内部的 A 色心的含量呈反比关系，A色心的含量越高，紫外荧光强度越低。

荧光对钻石品质的影响？

人们普遍认为荧光的存在降低了天然钻石的颜色等级，因此荧光钻石的市场价常常被低估。

但是对于色级比较低的钻石，这类钻石往往带有明显的黄色调，如果具有中等以上的蓝色荧光，则会中和掉自身的黄色调，而使得钻石颜色更显白，此时荧光则属于加分项。

因此钻石荧光并不是绝对的越弱越好，需要结合其他方面综合来看。

有荧光的钻石怎么选？

1. 弱荧光

2. 中荧光

小部分中荧光的钻石，对高色段钻石的通透性会有一定影响，但在价位上也并没有太大的优势。综合考虑之下，最好尽量避免选择H色之前的中荧光钻石。
