1.  优质钻石有何特征?


 

 

CUT

車工

 

 

Not to be confused with the shape of the diamond, CUT refers to the arrangement of a diamond’s facets. CUT is the most important of the four qualities (4C’s) because it determines the optimum combination of brilliance, scintillation and fire. This combination has the greatest effect on a diamond’s beauty. CUT is the only quality under man’s control.

 

车工并非是钻石的形状,而是指有关切割钻石刻面角度与比例的工序。车工能直接影响钻石的亮光、闪光及火光,因此过程极其重要。而车工是四大条件中唯一一项受人为影响。
