GIA的鑽石分級表

每一粒鑽石都不同,但都使用相同的鑽石分級標度進行分級。鑽石的內在質量取決於克拉重量,切工,淨度和顏色。 GIA已開發了鑽石定級標尺,該標定了鑽石行業的標準,甚至可以作為其他鑽石定級實驗室開發的其他鑽石定級標尺的基準。鑽石分級等級適用於鑽石的顏色淨度,並且在確定鑽石價值方面起著至關重要的作用。

鑽石分級等級:淨度

在鑽石分級等級上,從“內部無瑕”到“ SI3”範圍內的光譜評估淨度,顯示肉眼可見的瑕疵。實際上,大多數鑽石都會有一定程度的瑕疵,這是每顆鑽石都要經過的形成過程的一部分。瑕疵包括內部的內含物和外部的瑕疵。鑽石的價值在很大程度上取決於根據鑽石等級等級評估的淨度。瑕疵越少,它越稀有且變得越有價值。請注意,某些鑽石切工(如祖母綠切工)傾向於更容易顯示出內含物,而其他鑽石形狀則更好地將其隱藏。

鑽石分級等級:顏色

實際上,當按鑽石分級等級評估顏色時,我們會查看沒有顏色。無色鑽石非常稀有,並具有明亮明亮的火彩。顏色分級範圍從D到Z,其中D為無色,Z具有可見的淡黃色調。但是,這不適用於彩鑽。由於在這種情況下更需要顏色的強度,因此它們以不同的鑽石分級等級進行分級。如果您了解鑽石的顏色和淨度,則可以開始使用鑽石價格表。所有鑽石價格均按克拉數(按克拉重量)列出。由於鑽石的顏色和淨度各不相同,因此每克拉價格也各不相同。正如您將看到的,2克拉D色無瑕3克拉J顏色SI2更有價值。顏色和淨度對於鑽石的美感,獨特性和價格至關重要。

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. Both were absolutely flawless. I will continue to sing them praises and will most definitely purchase from them again in the future. Thank you again!

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.
