1.  優質鑽石有何特徵?


 

 

CLARITY

淨度

 

 

CLARITY is the degree to which identifying characteristics known as inclusions are present in a diamond. A “flawless” diamond has no internal or external flaws which are visible under 10-power magnification.

 

淨度是指鑽石內蘊含多少細微天然物質,一顆完美無瑕的鑽石,儘管放到10倍放大鏡下,亦絕不會發現半點雜質。
