COLOR, CLARITY, CARAT-WEIGHT AND CUT.


1.  優質鑽石有何特徵?


 

 

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.

 

車工並非指鑽石的形狀,而是指有關切割鑽石刻面角度與比例的工序。車工能直接影響鑽石的亮光、閃光及火光,因此過程極其重要。而車工是四大條件中唯一一項受人為影響。
