我想問下...一粒10卡普通的鑽石 要幾多錢??

同等重量的鑽石，價值會跟據其顏色及淨度而有所不同。

顏色等級分為：
D, E, F, G, H, I = Colorless (White)
J, K, L = Near Colorless (White)
M = Faint Yellow
N, O, P, Q, R = Very Light Yellow
S, T, U, V, W, X, Y, Z = Light Yellow

淨度則跟據含雜質量多少，而分等級如下：
F = Flawless
IF = Internally Flawless
VVS1 = Very Very Slightly Included #1
VVS2 = Very Very Slightly Included #2
VS1 = Very Slightly Included #1
VS2 = Very Slightly Included #2
SI1 = Slightly Included #1
SI2 = Slightly Included #2
I1 = Included #1
I2 = Included #2
I3 = Included #3

以顏色和淨度的中等級數 L 和 VS2 來計算，
10 卡的鑽石約值 140 萬元。

可到以下的網址，計算不同重量、顏色和淨度的鑽石約值多少。

當然鑽石的切割也會影響其價值，即鑽石的價值取決於 4C，請參看以下網址：

希望這些資料可以幫到你吧。

一卡普通質數既都起碼４－５萬．有証書更貴．我家姐結婚時買左粒４卡．唔係全美 tim 喎．２０萬．故１０卡一粒過的話．估計要成百萬.
