Dear Sam,

If the GIA cert marked the cut grade is Excellent, is it mean the depth and angel ratio of the diamond is great and 能散發出火彩? Or they are not directly related, the diamond depth will still be too depth or thin, 光線就可能從底部漏走? Thanks for you advice.

HI，

如果CUT GRADE 是EXCELLENT，他的切割角度合符標準會令到鑽石火彩，亮度都會很好，
你可以看看GIA 什麼評估！
