底线的推荐:

有些鉴定中心很严格,有些很宽松。但是无论怎么样,你只要在购买钻石时支付正确的价格就可以了。J

如果你在网上盲目的购买(非常推荐使用 James Allen的钻石切割观察工具),然后要坚持GIA,因为它是最可靠的鉴定中心。我个人已经看过了钻石鉴定中心犯过的重大失误(当然,也包括GIA)。

当你有一个钻石公司的时候,那么每个月你都会送到鉴定中心上千颗的钻石,5%的矛盾也不是一个很大的问题。但是,作为一个消费者,为什么要冒这5%的风险呢?只是时刻提醒自己,你购买的是钻石,而不是一张纸。

名誉的重要性

当挑选一颗钻石的时候,颜色净度等级(有些时候也包括切工)的可信度就直接和钻石鉴定中心的声誉对等。

首先要一致性

但是,有件事一定要注意,当我们讨论不同的鉴定中心的时候,唯一的问题不是他们有多么的严格,而是他们前后的一致性。

如果一个鉴定中心持续的给出比其它鉴定中心高一个等级的颜色,那么这个鉴定中心就不意味着缺乏“真实性”。

钻石等级的评定是主观的

所有的钻石等级的评定都是主观的,正好和大众的观点相反,世界上没有一个权威的组织来精确的定义什么是“G”颜色,什么是“SI1”净度。

所以如果一个鉴定中心持续的说这就是“G”颜色,而另一个鉴定中心说这就是“H”颜色,那么这也是完全可以接受的,也是合理的 — 只要他们持续的这么给出鉴定结果。

价格比证书更重要

作为消费者的你需要记住一件很重要的事情:价格是要和钻石吻合的,无论它有没有证书。

不同的鉴定中心给出不同的鉴定结果 

当然,认识到每一个鉴定中心都有自己的怪癖也是很重要的事。有些在颜色上很宽松。有些在净度上很宽松。有些则总是在某个范围提升颜色的等级,然而其它的鉴定中心则喜欢特定的杂质分布。

聪明的钻石公司会利用这些知识(通过每个月送到不同的鉴定中心上千颗的钻石来获得利益)来过的最好的结果。
