底线的推荐:

如果你的钻石是H,I,或是 J颜色,那么寻找一颗带有中度荧光的钻石来增加点奖励 — 它可以让你的石头看起来更白一点儿。如果没有,你的石头也是很好看的。

如果你要购买的钻石是 G或是更好的颜色,那么钻石的荧光要么是弱荧光,要么就没有荧光。否则,就考虑 Brian Gavin的蓝色系列的钻石,从中找到一颗 I或是 J的钻石,这才是最好的价值。

什么是钻石的荧光?

荧光讨论的是当钻石受到紫外线照射时的反映。紫外线可以让白色更白,你的牙齿更白和你的黑光海报发光。

一些钻石,当你把他们放在紫外线下时,会发出不同的光。我是不打算解释为什么会这样。如果你有兴趣,可以谷歌“钻石荧光”,我确定你可以找到足够的科学信息来解释发光的现象。

99%的时间,发出的都是蓝色光,但是极少数情况下,钻石会发出白光,黄光,绿光,甚至是红光。但是故事并不终止于此。

强蓝色荧光

总之,如果钻石只在紫外线下才发光,这也只有当某人整天在黑光灯下的黑暗房间里才会发生(舞会俱乐部,迪斯尼的旋转木马等等。)。

但是事实是,大多数的钻石都会呈现出一点强蓝色荧光 ,在正常光线下会有严重的朦胧感。

如果你做过功课了,也谷歌了钻石的荧光,那么你可能会读了一篇叫做GIA研究的文章,他们声明即使是强蓝色荧光对于普通的钻石消费者来说也是不易察觉的。

高强度荧光就意味着钻石看起来更朦胧

我可以非常明确的告诉你,他们的研究声明是废话。在我的职业生涯里已经见过了许多就算不是成百上千的钻石,我也可以毫无疑问的告诉你如下的观点:

  • 强/非常强的蓝色荧光的钻石通常看起来很朦胧
  • 中度蓝色荧光的钻石很少会看起来朦胧
  • 微弱/弱的蓝色荧光的钻石绝对不会看起来朦胧

荧光可以改善颜色

尽管如此,这个研究中也有一个声明是正确的。荧光通常会改善钻石的外观颜色。

所以我在上面的底线推荐中建议,如果你要购买一颗H颜色或是更低等级的钻石,尝试寻找一颗带有中度蓝色荧光 的钻石。

对于强蓝色荧光的建议我是持保留意见的,因为就算是低等级的颜色有时候也会看起来奶白色或是有朦胧感,只有它们有强蓝色荧光。

关于荧光的犹豫

当要购买一颗高等级颜色(G颜色或是更高)的钻石的时候,我也很犹豫是不是要建议购买带有中度蓝色荧光的钻石。因为少数情况下,当颜色等级很高的时候,就算是中度蓝色荧光也会展示出奶白色或是朦胧感。

当然,如果你的购物时面对面而不是在线购买的话,那么你就可以特别要求一颗带有强蓝色荧光的钻石。

这会更加的便宜,而且你是面对面的在那里,你可以亲自看到这颗钻石是否有奶白色或是朦胧感。

Brian Gavin的蓝色系列

一个很有趣的选择就是如果你要从Brian Gavin的“蓝色”系列中购买钻石,这些石头都是由Brian Gavin亲自挑选的,它们是没有任何的奶白色或是朦胧感。

荧光通过使钻石看起无色来改善石头的外观,它们就像具有“签名”的八箭八心完美切割的钻石那样闪耀,只有一个例外 — 它们更加的便宜。

自从2012年开始我们就强烈推荐这些钻石,而那些听从我们意见的人在这点上也都非常的满意。

当地购买 VS 在线购买

如果你考虑在当地购买,你可能会通过购买一颗强蓝色荧光的钻石而赚到,它还是要比你在线购买一颗中度蓝色荧光或是更低等级的荧光的钻石要便宜。

不幸的是,就算James Allen有最好的摄影技术,也无法展示钻石在实际的太阳光下的样子。
