The 4Cs Guide of Diamonds

An international measure of quality

Swarovski Created Diamonds Jewelry Read the Buying Guide

What Are the 4Cs of Diamonds?

Universally recognized, the 4Cs are a guiding light in the world of diamonds, helping to determine the quality and value of each stone - the 4Cs stand for color, cut, carat, and clarity. The laboratory grown diamonds in the Swarovski Created Diamonds collections are graded against these 4Cs by IGI, the International Gemological Institute. The laboratory grown diamonds in these collections are of very fine quality: G+ in color and VS+ in clarity.

What is diamond clarity?

Diamond clarity is a measure of the purity of the stone graded by the visibility of two types of characteristics - inclusions and blemishes. In order to assess clarity, the diamond is inspected under 10x power magnification. The number and nature of external (blemishes), and internal characteristics (inclusions), as well as their size and position, determine the clarity grading.

Clarity Principles and Factors

The clarity of a laboratory grown diamond is judged by its flaws, which means the inclusions and blemishes that give it unique character and charm. Discover more about diamond clarity below.

INTERNALLY FLAWLESS

The highest possible clarity of diamond is an internally flawless (I.F.) stone. These are incredibly rare and most mined and laboratory grown stones have inclusions.

To The Naked Eye

While almost all diamonds are flawed, those graded between I.F. and SI 2 have inclusions that aren’t visible to the naked eye, only under magnification.

Types of Inclusion

The different types of diamond inclusion include feather, pinpoint, cloud, and metallic. Metallic inclusions are only found in laboratory grown diamonds.

A TRICK OF THE LIGHT

Inclusions and blemishes can have an impact on the way a diamond reflects and absorbs the light.

Diagramma di purezza del diamante

Scala e gradi di purezza del diamante

La scala di purezza del diamante va da I.F a I3 e si basa sul numero di inclusioni e imperfezioni riscontrate in ogni pietra. I gradi di purezza del diamante sono determinati in condizioni di visualizzazione standard con lente di ingrandimento 10x. La categoria I.F indica un diamante privo di inclusioni interne mentre, all’altra estremità del diagramma di purezza del diamante, I3 indica l’inclusione di un’imperfezione visibile. I diamanti completamente privi di inclusioni sono estremamente rari. Quasi tutte le pietre, compresi i diamanti creati in laboratorio, presentano inclusioni di qualche tipo.

Diagramma e simmetria del taglio del diamante

Che cos’è il taglio del diamante?

Il taglio si riferisce al modo in cui le sfaccettature del diamante interagiscono con la luce per rivelarne il fulgore interiore. Il taglio conferisce ad ogni pietra una personalità unica, mentre il perfezionamento delle proporzioni, la simmetria e le angolazioni tagliate con precisione dei diamanti creati in laboratorio conferiscono loro una brillante lucentezza.

Parametri e fattori di taglio

La qualità del taglio di un diamante creato in laboratorio è determinata dalle sue proporzioni, dalla sua simmetria e dalla sua lucidatura. Un taglio a regola d'arte crea molteplici sfaccettature che assorbono e riflettono la luce e fanno brillare la da ogni angolazione.

Near colorless

K-M

Very light color

N-R

Light color

S-Z

Diamond color scale and chart

Diamond coloring is rated on a scale from D to Z, with D clear ice white with no hint of yellow, while those rated Z are shades of yellow and brown. Each letter range on the chart denotes a shade of stone, with those rated D to F appearing colorless, through to S to Z appearing in shades of light yellow or brown. Swarovski only accepts the finest laboratory grown diamonds in its collections, meaning they range from colorless to nearly colorless diamonds (D-G).

Color Principles and Factors

Colorless stones are the most desirable in the world of diamonds and they are extremely rare. Swarovski Created Diamonds are evaluated against the standardized diamond color scale.

COLORLESS DIAMONDS

Truly colorless diamonds are extremely rare. Also known as ice white, D diamonds are also the most expensive diamond color to buy.

FIND YOUR SHADE

Finding a D diamond color isn’t always important when selecting your stone. A warm white might suit your individual style more than an ice white.

CONTROLLED ASSESSMENT

Each diamond’s color grade is assessed in a laboratory using controlled lighting, with the stone faced down, and with master samples used for comparison.

BLEMISHES

Laboratory grown diamonds do not include any intentional blemishes or the color defects that can come from the use of poorer quality carbon seeds.

What is diamond carat weight?

A carat is a unit of weight used specifically to measure precious stones including laboratory grown diamonds. A diamond may have a higher carat weight without appearing larger, and two diamonds of the same carat weight can vary in size if one is cut deeper than the other. One carat weighs 1/5 of a gram and is divided into 100 points.

Diamond Carat Weight

Laboratory Grown Diamond Carat Scale

The carat measurement is derived by the word ‘carob’, a seed that was used as a diamond weight reference for traders in the ancient world. Carats are an international standard unit of measurement for the weight of a diamond. One carat is equal to 200 milligrams, so a 5 carat diamond will weigh one gram. The diamond carat does not refer to the size of a stone, simply how much it weighs. Diamonds usually become more expensive as their carat increases.

Frequently asked questions

Diamond 4Cs FAQs

What are the 4Cs?

Every diamond varies slightly from the next and has its own individual distinguishing characteristics. Laboratory grown diamonds are 100% diamonds, and just like mined diamonds our laboratory grown diamonds are evaluated according to the 4Cs of diamond grading. The 4Cs are color, clarity, cut and carat weight, and they are the globally accepted standards used to assess the quality of diamonds.

Is diamond clarity important?

The higher the clarity grading, the less inclusions or blemishes a diamond has, making it a higher-value diamond than one with a lower grading.

What is the highest diamond clarity?

ダイヤモンドのクラリティは透明度の事をいい、インクルージョン（内包物）とブレミッシュ（表面の疵）がどれだけ少ないかで評価されます。クラリティを評価するには、ダイヤモンドを10倍拡大下で鑑定します。表面のブレミッシュと内部のインクルージョンの数やタイプ、サイズ、位置などによってグレードが決まります。
宝石鑑定士は、ダイヤモンドを最高品質のIF(インターナリーフローレス)からI3（インクルーデッド）で評価します。

ラボラトリー・グロウン・ダイヤモンドは内外部にまったく傷がないのですか？

不是，幾乎所有的鑽石 (開採的或實驗室培育的) 都有內含物。培育鑽石可能會含有金屬雜質。如果專家在鑽石中發現金屬痕跡，便可以假定這是培育鑽石。雖然培育的鑽石確實存在瑕疵，但 Swarovski Galaxy 系列只選用經由IGI國際寶石研究院根據 4C 標準認證的優質培育鑽石，以確保 Swarovski Created Diamonds採用的都是品質優良的鑽石。

培育鑽石會變混濁嗎？

不會，培育鑽石不會隨著時間的推移而變得混濁。除了來源，它們與開採鑽石在其他方面100% 相同，具有相同的物理和化學特性，不會隨著時間的推移而退化或改變外觀。若使用品質不佳的鑽石種晶，某些實驗室培育的鑽石會有明顯的缺陷，例如：因鑽石中的雜質或晶體結構不完善造成的色差。Swarovski Created Diamonds 首飾所採用的培育鑽石具有極高的品質標準，不會出現反常或有問題的特徵。

培育的鑽石如何認證和分級？

Swarovski Created Diamonds 首飾中的培育鑽石均由經驗豐富的寶石學家手工挑選和檢驗，以確保這些鑽石符合我們的高品質標準。 Galaxy 和 Eternity 系列的每一件首飾都附有IGI國際寶石研究院的數位實驗室報告。

什麼是鑽石切刻面？

鑽石切刻面是指構成鑽石形狀的每個平面。每顆鑽石都有多個切刻面，使其能夠吸收和反射光線。

如何判定鑽石的切割品質？

我們通常認為鑽石的切割是指鑽石的切割形狀 (圓形、心形、橢圓形、橄欖形、梨形) ，但鑽石切割實際上指的是鑽石切割面與光線的相互作用。鑽石的切割是衡量鑽石形狀、幾何形狀和表面處理的品質。圓形明亮式切割鑽石的切割等級從理想 (最好) 到不良都有。 Swarovski 對切割品質毫不妥協，以確保我們所有的培育鑽石都具有出色的光線效果和閃耀程度。

什麼是最佳鑽石切割？

切割是指鑽石的切割面如何與光線相互作用，以顯示其內部的火光。切割的程序賦予每顆鑽石各自的獨特性，Swarovski Created Diamonds 培育鑽石出衆的比例、對稱性和精準的切割角度讓鑽石綻放璀璨的光芒。最佳的切割方式是在寬度和深度之間取得平衡，以形成對稱，既不會太淺，也不會太深。這會讓光線在穿過鑽石時創造精巧的折射點，將光線反射到鑽石內部，增強鑽石璀璨耀眼的亮度。

如何判定鑽石的顏色？

顏色是指白鑽固有的天然色調。顏色分級的產業標準是將每顆鑽石與對照組鑽石進行對比評估，然後提供以英文字母 D (無色) 到 Z (淺黃色或棕色) 的區分等級。
鑽石越接近無色，品質就越好。

實驗室製造的鑽石會有瑕疵嗎？

若使用品質不佳的鑽石種晶，某些實驗室培育的鑽石會有明顯的缺陷，例如：因鑽石中的雜質或晶體結構不完善造成的色差。Swarovski 不會販售具有反常、有問題特徵的培育鑽石。

什麼是鑽石克拉重量？

克拉是一種重量單位，專門用來衡量包括培育鑽石在內的珍貴寶石。克拉數較高的鑽石，外觀看起來並不一定較大；兩顆克拉數相同的鑽石，如果其中一顆切割得比另一顆深，它們的大小會不相同。一克拉的重量是 0.2 公克，區分成 100 分。

鑽石的克拉重量是什麼？如何測量，重要性為何？

克拉重量是鑽石的標準重量單位，也是分級過程的第一步。鑽石克拉重量是衡量鑽石重量的單位。每克拉可細分為 100“分”。這樣在測量重量時就可以精確到小數點後兩位。小於一克拉的鑽石重量可以只用“分”來描述。鑽石越大，克拉重量就越多，但只有您才能決定這對您來說有多重要。

鑽石的克拉重量愈大愈好？

這完全是取決於個人的問題。如果您正在尋找一顆較大的鑽石，您應該尋找克拉數較高的鑽石，因為克拉數表示鑽石的重量，因此也表示鑽石的大小。
