腰棱是鑽石連接頂部(冠部)和底部(爪齒)的部分。從頂部看時,腰棱提供了鑽石的形狀,從側面看時,它將圓頂與尖底分開。對於圓形切工,它是鑽石的一個非常重要的組成部分,因為它會影響總的切工等級。對於復雜的形狀,腰圍厚度不是問題。所有鑽石都有腰棱,但其尺寸和拋光度各不相同。腰棱負責鑲嵌和固定鑽石,因此它必須堅固且能夠承受對鑲嵌的衝擊。當您購買由認證機構分級的鑽石時,激光刻字就像位於腰棱上。

鑽石的腰圍厚度可能會以多種方式影響它,從外觀到耐用性。在投資鑽石之前了解這些事實至關重要。

克拉重量

對於預算有限的個人來說,腰圍寬度對克拉重量的影響非常重要(對於訂婚戒指,大多數買家都是這樣)。更大的克拉重量(因此價格更高)將來自更厚的腰棱,但鑽石在鑲嵌中看起來不會更大。即使對克拉重量和價格的影響很小,錢仍然花在了與寶石的美感或尺寸無關的東西上。 花式鑽石(例如馬眼形、心形或梨形切割)的角周圍較厚的腰棱可能會提供額外保護反對碎裂。 鑽石購買者最重要的方面是克拉重量。如果您正在尋找可能的最大的鑽石,那麼購買腰棱特別厚的鑽石並不合適不是最好的選擇。這是由於鑽石的腰棱非常厚,隱藏了大部分重量。從上往下看時,一顆重 1.5 克拉的鑽石 有異常厚的腰棱,另一顆重 1.3 克拉的鑽石有細的腰圍可能看起來大小相同。多出來的 0.2 克拉可能值幾百美元,但它的腰棱浪費了它。

光返回

鑽石的光彩來自於它的高光迴光。在理想世界中,光線進入鑽石,然後通過其檯面射出。它在離開鑽石時分散開來,賦予鑽石應有的閃耀光芒。如果沒有以適當的比例切割,非常厚或非常厚的腰棱可能會對光線性能產生不利影響。腰棱太厚,無法以理想的角度通過工作台充分反射光線。魚眼效應是由光線在石頭內部反射而產生的。腰棱很薄的鑽石可能有同樣的問題,但原因不同。

耐用性

因為鑽石意味著終生難忘,您應該在購買前考慮它們的耐用性。腰棱是影響鑽石壽命的鑽石特徵之一.極薄的腰棱會影響鑽石的耐用性,從而影響其使用壽命。雖然鑽石可能會伴您一生,但極薄的腰棱會形成較窄的邊緣,隨著時間的推移容易碎裂。如果您正在查看公主方形切割鑽石,請遠離極薄和極薄腰棱;公主方形切割已經有易碎的邊角,因此添加薄的腰棱和邊角會使鑽石更容易受到損壞。如果您的鑽石有較薄的腰圍,請選擇能夠保護鑽石的鑲嵌方式,例如包邊鑲嵌或鑽鑲。

火與光

鑽石周圍刻面的相對位置也受腰棱寬度的影響。這意味著厚度會影響鑽石的光性能和無意切割。具有極厚腰棱的鑽石將具有很高的亮度和火彩,但前提是切工得當。另一方面,較厚的腰棱將鑽石的重量集中在中心,使鑽石從上方看時顯得較小。在檢查腰棱特別厚的鑽石時,考慮鑽石的整體尺寸至關重要。如果它們在正確的範圍內,過厚的腰圍也不會有太大的不同。請記住,腰棱厚度將被評估並包含在鑽石的最終切工等級中。這意味著即使寬度不在理想範圍(薄 – 略厚)內,鑽石仍可被視為最佳切工並具有出色的火彩、亮度和閃爍度。

剪切

切工是 4C 中最重要的,因為它會影響光線的進入方式並從鑽石上反射出來。對稱性涉及鑽石腰棱與其切工質量之間的關係。 GIA 為圓形切割鑽石 基於其形狀的精確性和刻面的對稱性,其中包括腰棱。分級方法考慮了平均腰棱厚度以及最小和最大寬度。他們查看 16 個山谷位置,看看它們與鑽石的直徑。儘管任一極端的腰棱厚度並不必然意味著較低的切工質量,但精湛且 完美鑽石通常具有薄到稍厚的腰棱。

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.
