20分无证书的钻石如何辨真假?

20分无证书的钻石如何辨真假?对于30分或以上的钻石,除了有国际证书外,成品钻戒还拥有国检证书,这样很方便大家辨别钻石真假。但对于20分钻石,一般都不配备证书,这样的情况下应如何鉴别真假?

对于20分或以下的钻石,国家不强制要求出具钻石4C鉴定证书,但如果你在ROTASS诺塔思购买单颗镶嵌钻石首饰,都是可以出具鉴定证书。对于群镶类的钻石首饰,若有需要,也可以为大家去权威机构出具钻石真伪证书。这样方便大家鉴别钻石真假。

但对于一些不出具证书的20分以下钻石首饰,大家可以根据钻石的莫氏硬度,可以通过刻划玻璃,如果手上的钻石没有损伤并在玻璃上刻画出痕迹,那么基本能保证钻石的正品。但这个方法并不一定准确。

20分无证书的钻石如何辨真假?再教大家一个方法,无论何种赝品都没有钻石的硬度大。真品虽经长期佩戴,均不会有丝毫起毛现象。如果有条件的话,采用钻石笔在钻石首饰底面边缘上一试,就可立断真假,这是最保险也最可靠的鉴别办法。
