鑽石以克拉為單位稱重,克拉是標準計量單位。術語“尺寸”經常被用來誤解鑽石克拉的含義,克拉實際上是衡量鑽石重量的單位。

鑽石的克拉重量是衡量其大小的百分比。此外,一克拉(1 克拉)鑽石重約 0.20 克(200 毫克)。

了解鑽石克拉 – 4cs

為了準確測量,鑽石的每克拉分為 100 分,其中 1 分等於 0.01 克拉。

這意味著就克拉重量而言,半克拉 (1/2) 鑽石等於 50 分或 0.50 克拉鑽石,而四分之一克拉 (1/4) 鑽石等於 25 分或 0.25 克拉克拉鑽石。克拉和小數用於表示大於一克拉的鑽石的重量。例如,一顆 1.08 克拉的石頭將被稱為“一點八克拉”。

在確定了 4c 的切工、顏色、淨度之後,克拉成為選擇鑽石的最吸引人的因素。因為這決定了鑽石的最終價值。鑽石價格隨著鑽石克拉重量的增加而上漲。尺寸確實很重要,但更大的鑽石總是受到更多人的追捧。但是,您應該知道,相同克拉重量的兩顆鑽石的價格可能會因其他三個特定於鑽石的因素(切工、顏色和淨度)而有很大差異。

因此,雖然克拉重量對鑽石外觀的影響最小,但卻是決定鑽石價格的最重要因素。

直徑 (MM) 和每克拉價格變化

要了解鑽石的價格,我們需要看一個示例。為簡化起見,我們將對下列四顆鑽石使用 G 顏色、Vs1 淨度和出色的切工等級。請記住,鑽石的價格受多種因素影響,包括其克拉重量。下表旨在讓您大致了解基於尺寸的鑽石價格。

克拉重量直徑 (MM)每克拉價格總價
0.50 克拉5.1 毫米3000 美元1500 美元
1.00 克拉6.4 毫米6000 美元6000 美元
2.00 克拉8.1 毫米12000 美元24000 美元
3.00 克拉9.3 毫米18000 美元54000 美元

價格和直徑隨著克拉重量的增加而增加,如上表所示。

讓我們首先查看作為克拉重量 (CtW) 函數的直徑 (MM) 增加百分比。

許多人錯誤地認為半克拉 (0.50) 的重量與一克拉 (1.00) 的重量相同。直徑(毫米)差異不是它的一半。另一方面,0.50 克拉的圓形鑽石的直徑僅比 1.00 克拉的圓形鑽石稍大。這兩顆鑽石的毫米差只有1.3毫米,不足25%。 (從 5.1 毫米到 6.4 毫米)因此,即使克拉重量增加一倍,直徑也不會增加一倍。

現在,讓我們看看鑽石的價格和大小之間的關係。

從這張表中我們可以看出,價格隨著克拉重量的增加而增加。增加的克拉重量與每克拉價格之間存在直接關聯。例如,每克拉的價格從 6,000 上升到 18,000。然而,隨著尺寸的增加,鑽石的總價值會急劇增加。這意味著 0.50 克拉鑽石的價格約為 1500 美元(0.50 美元 x 3000 美元),而 2 克拉鑽石的價格是 16 倍(2.00 美元 x 12000 美元)。鑽石越大,價值越高。

克拉重量點如何影響價格

大多數鑽石不是 0.69 克拉或 0.99 克拉,而是被切割成 0.70 克拉或 1.00 克拉的重量。但最重要的是要知道,0.98-0.99 克拉比 1.00 克拉好。大小差異將是微不足道的,但您節省的錢將是可觀的。

克拉重量每克拉價格
0.90 克拉 – 0.99 克拉E VVS 2 – 6000 美元
1.00 克拉 – 1.49 克拉E VVS 2 – 8000 美元

換言之,一顆 0.98 克拉的鑽石售價為 5,880 美元,即每克拉約 58 美元。相比之下,如果您要購買 1.00 克拉的鑽石,則需要 8000 美元(假設鑽石具有相同的切工、顏色和淨度)。由於成本較低,應認真考慮圓形鑽石點。

雖然鑽石的克拉重量對其價值的影響最大,但切工對其整體吸引力的影響最大。此外,鑽石的價格會隨著克拉重量和尺寸的增加而上漲,因為更大的鑽石更有價值。

Nissan, David and his team were extremely accommodating, understanding and patient with our purchase. They took the upmost care to find the best solution for our needs and went above and beyond normal ‘customer service’ standards. I have absolutely no qualms recommending their products and services.

Bought a beautiful stone here for an engagement ring. I was a little apprehensive since you’re buying something unseen. But Cid made it easy. In fact, Nissan, the owner also gave a call to make me more comfortable. They sent me the stone to take to a local jeweler with only my Amex in case I bailed on them.
