钻石中的价格差之谜

钻石中的价格差 从不在于钻石是否有证书或报告。 （钻石的报告书的售价相对钻石的总价是十分低的）。关键是在于钻石4C 的真正质地 1。切割 2。重量 3。颜色，4。净度

4C 中，钻石的 “重量” 最容易界定。 “颜色” 也可以以 “彩色衡量机” 或 钻石“比色石”而准确判断出来。 “净度”是主观的，但准则是由世界主要的实验室定下并接受。有信誉的实验室包括AGS和GIA已经运用钻石的3D立体比例以提供一个更准确的钻石切工级别。

有些人可能看到不同的“钻石报告”如(AGS, GIA, HRD IGI EGL NGTC 等) 4C一样 但价格大有不同。
例如：
1.02克拉 GVS2 附有 AGS 3个 完美 (IDEAL)　和　
1.08克拉 GVS2 附有 GIA 3 个 顶好 (EXCELLENT）和
1.07克拉 GVS2 附有 IGI 3 个 很好 (EXCELLENT）

以上3 颗钻石的克拉市场价格（USD/CT）分别为 ，USD6336， USD5760 和 USD5040。 个有% 10 到 % 26 的成本差异。

钻石报告本身的成本几乎相同。 （钻石的报告书的售价相对钻石的总价是十分低的）
AGS USD114（DQR大证）到 131 （DQD大证）
GIA USD81 （DOSSIER小证）100 （大证） ，
HRD EURO 75 （US111）大证
IGI & EGL, NGTC 价格比较有弹性，所提供的折扣也相对较大

关键是各大实验室 （AGS，GIA，HRD，IGI，EGL，NGTH 等）在市场上的定位。因而导致钻石的价格差异

例如，同样的钻石。 1. 01 GVS1
每个实验室会应本身市场定位而分配一个不同的等级（无论是在颜色，净度，切割，打磨，或对称）给这颗钻石，从而导致钻石价格差。

Price differential of a diamond

The difference is never in the question of whether the diamond has a report or not. (The price of the diamond report is relatively low compare to the value of the stone). The key is in the true 4 C’s of a diamond. 1。Cut， 2。Clarity 3。Color， 4。Weight

Among the 4 C’s, Weight is easy to define with diamond scale. Color can also be measured accurately by color machine or the “diamond master set”. “Clarity” is subjective but the guideline was accepted by major laboratories of the world. Reputable Laboratories includes AGS and GIA is implementing 3 dimensional measures on the proportion of the diamond in order to give a more accurate diamond cut grade.

Some people might be puzzled by the huge price difference for the “same” (4 C’s) stone with different report.

For example:

1ct DIF with GIA EXEXEX compared with
1ct DIF IGI EXEXEX, the price difference cab be as high as 20-30%.

Again, the cost was never in the cost of the report itself. The key is on the positioning of the Diamond Grading Laboratories (AGS, GIA, HRD, IGI EGL NGTC etc) in relation to the reports issued. Thus creates the difference in price of a diamond

Same diamond eg. 1.01 GVS1 VG G EX
Each Laboratory might assigned a different Grade (whether it is in the color, clarity, cut, polish, or symmetry grades) based on the Lab’s positioning in the market.
Price difference was the result of such positioning.
