钻石价格与钻石证书之间的关系

钻石恒久远,一颗永流传。一句简单的广告语让全世界的人都知道了钻石的存在,更是受到了万千女孩的喜爱。钻石估计是那么多礼物中最能讨女孩子欢心的礼物了,但钻石价格与它的证书各类有着千丝万缕的联系,不一样的钻石证书,价格也是不同的,今天我来给大家讲讲钻石价格与不同证书的关系。

 

一颗带IGI证书,一颗带GIA证书,两个证书的钻石4C完全一样,比如同为1.01克拉,G色,VVS2,EX切工,但带IGI的证书钻石要便宜25-30%左右,价格差就在1万元以上。IGI钻石证书对钻石颜色的把握要求会低些,而通常一个色级差造成的差价就在10%以上;根据国内钻石鉴定机构专家的说法,国内钻石评定等级是以GIA标准为参考,从钻石分级的仔细程度来说,经过对上千颗国际钻石做比较,GIA分得更细,总体好些,钻石等级相应高一些,人为误差更少一些。像GIA与另外一家HRD国际证书,GIA的颜色普遍比HRD的高半级左右水平,HRD证书比GIA证书的钻石一般低10%-15%;GIA是全世界最权威的钻石鉴定证书,不仅是钻石4C标准的制定者,而且是一家独立的非盈利性组织,以它的公正而闻名,其钻石分级报告最严谨与到位。而且GIA证书国际通用,几乎每颗钻石的腰线上都刻有GIA的证书编号,这样不仅保证了钻石的独一无二,证书的钻石在腰部有镭射防伪标签,只要输入GIA激光编号和钻石大小就可以上网查验真伪,很难出现假货。
