  • 对称性(比例):“好”或是更高的等级。

什么是钻石的对称性?

钻石的对称性讨论的是钻石的切割面有多么的整齐。顶部切割面的边缘是否在腰部和底部切割面的边缘对齐?切割面是否对称的分布在钻石上?

对称性是否比抛光更重要?

这个问题的答案很简单:并不总是。可以看下右边的图例。

上面提到的每一个情况(尖底偏离中心,桌面偏离中心,瓣面形状不良,腰部不圆,冠部与底部没有对齐,波浪形腰部)都可能影响钻石的魅力。这也不是问题所在。

告诉你对称性的不同

问题的所在就是,以我6年以上的专业钻石经验来说,也很难讲出“好”和“完美”等级的对称性的不同。

你也只能在“一般”或是“不好”级别的对称性的钻石中观察到在图例中的那些失败的例子。抛光也是一样的问题,所以没有必要花费额外的开支去购买“非常好”或是“完美”等级的钻石。
