钻石的重量是钻石最主要的评价因素,通常钻石重量用克拉(ct)表示,标准的1克拉=200毫克=0.2克、1克拉=100分。虽然钻石的切割工艺各异,但是钻石直径和重量之间还是有一个大概的比例,今天小微与大家分享一下这个钻石直径与钻石重量示意图的与对照表!让你轻松了解钻石的直径与重量的关系。
当然,这里所说的钻石大小对照表是指圆钻,圆钻是常见的钻石切工,而其他异形钻的钻石大小标准又不一样了,相对来说,异形钻会比圆钻更显钻,但是圆钻更加精致漂亮。

从钻石大小对照表中可以看出,0.32克拉的钻石对应的钻石直径为4.55毫米,在视觉上不会觉得钻石很小,所以0.3克拉以上的钻石是更多人的婚戒之选。0.4克拉钻石直径为4.84mm,0.52克拉钻石直径为5.25毫米,0.72克拉钻石直径为5.89毫米,要想让钻石戒指更加显钻又追求性价比的话,小微建议选择0.5-0.7克拉之间的钻戒。
看完钻石大小对照表,你心中有自己的想要买的钻石大小标准了吗?在购买钻石的时候,我们经常听到多少分的钻石,其实分也是钻石的重量计量单位,100分就等于一克拉的钻石。钻石大小可以参考钻石鉴定证书。
