底线的推荐:选择最低的颜色净度,只要看起来是好看的,选择尽量大的克拉重量,只要在你的预算之内。但是总是不忘切工,因为切割不好的较重的钻石可能看起来比切割很好的较轻的钻石更小。

什么是钻石的“克拉”重量?diamond-cut-diagram

根据维基百科,钻石克拉这个术语来自希腊语,意思是“长豆角书的果实”。

在古代,长豆角的种子常用来作为测量重量的一个标准,因为种子的大小几乎都是一样的。这就提供了一个天然的测量标准。

在1907年的第四届重量和测量大会上,决定了现代钻石克拉重量就等于200毫克。从技术上就称作标准的 1克拉,这就成为了使用至今的钻石克拉重量的标准。

为什么钻石的克拉重量重要?

事实是,这没有什么关系。试想一下,当你看到戒指里镶嵌的钻石,你眼睛看到的是什么?你的眼睛能看到重量吗,或是能看到具体的大小吗?显然,你只能看到物理的方面 — 反射回来的光线并不携带重量的信息。

如果你再多考虑下,你的眼睛也不能看到钻石的整体尺寸,因为钻石的多部分都藏在了珠宝里。当你看到一颗钻石的时候,你所能看到的钻石的尺寸就是它的上半部的表面。

对于圆形钻石,看到的就是直径,而其它的形状就是长和宽的综合感觉。为了之后的文章,简单的来说,我也拿直径来说明,但是我所说的同样也使用与其它形状。

克拉和直径的关系

现在,在钻石克拉重量和钻石的直径之间是有一个直接的关系的。就像一个0.05克拉的钻石的桌面是一定不会比1.00克拉的钻石的桌面大。

但是因为切工可以非常优秀,这就使钻石在任何的克拉重量下拥有多种的直径尺寸。

根据我在Leo Schachater的工作经验,一颗1克拉的钻石的直径可以从5.60mm(非常不好的钻石深度)一直到6.60mm(一颗浅而“平坦”的钻石)。

切割等级和重量的直径

所以你可能看到,重量对于你来说是很重要的,因为它决定了你要支付多少的费用,那么你要注意的就是钻石的切割等级和直径。

总之,你是想要一颗0.90克拉的Brian Gavin签名完美切割的钻石,拥有6.2mm的直径而且看起来很好还便宜,还是想要一颗看起来不好看,直径只有6.1mm的1克拉钻石?
