心形裸钻要怎样挑选

钻石我们现在都比较熟悉,我们经常会在市面上见到一些钻石或者钻石首饰,身边佩戴钻石首饰的人也有很多,但是我们在市面上或者身边的人佩戴的钻石首饰上的钻石多半为圆形钻,很少见到其他形状的钻石,其实钻石还有心形钻、梨形钻等等,近年来,心形钻比较受到大家的喜爱,今天来给大家说一下心形裸钻要怎样挑选。

心形钻石的净度方面和圆钻相同,从IF到P3级别的都有,SI2以上净度钻石比较适合选做钻戒,30分以上钻石建议VS2净度等级以上钻石,30分以下可以考虑SI1净度钻石;和圆钻一样,1克拉心形钻石为0.2g;与圆钻相同,从D色—K色,高性价比可选H色,高品质可选D色左右,一般GIA钻石在进行国检的时候会发生掉级现象,无需惊慌,只要证明钻石是真钻即可;不论是圆钻还是心形钻或是其他形状钻石,都会有polish的参数,抛光影响的是钻石的光面效果,选ex的是最佳选择;心形钻石讲求对称,一般来说ex的对称性是最好的,VG是次之,从VG开始基本上是可以看到心形钻石的不对称边缘的,从美观角度考虑,这个对称方面必选ex系的;目前市场上心形钻石长宽比大多在0.9-1.2左右比较合适,行家还会根据数据选胖心形钻石,一般来说胖心形钻石比较适合做戒指佩戴,整体会显得饱满美观;大家要挑选有钻石鉴定证书的钻石,通过证书上供的瑕疵图基本上可以判断钻石的综合品质,为选钻石提供基础依据。
