What Are the 4Cs of Diamonds?
Title:
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.

Diamond Clarity Chart
Title:Diamond clarity scale and grades
Subtitle:
The diamond clarity scale runs from I.F. to I 3 and is based on the number of inclusions and blemishes found in each stone. Diamond clarity grades are determined under standard viewing conditions with 10x magnification; I.F. is used to represent an internally flawless diamond, while at the other end of the diamond clarity chart, I 3 stands for the inclusion of a visible blemish. Truly flawless diamonds are extremely rare – almost all stones, including laboratory grown diamonds, have inclusions of some kind or other.
What is diamond cut?
Cut refers to how a diamond’s facets interact with light to reveal its internal fire. It is the cut that gives each stone its personality, and perfecting the proportions, symmetry, and precision-cut angles of laboratory grown diamonds gives them their brilliant shine.
Cut Principles and Factors
Title:
The quality of how a laboratory grown diamond is cut is based on its proportions, symmetry, and polish. An expert cut creates a multitude of facets, absorbing and reflecting the light so the stone shimmers from every angle.

D-F
Near colorless
G-J

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
Title:
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.

Diamond Carat Weight
Title:Laboratory Grown Diamond Carat Scale
Subtitle:
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?
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 grade.
Gemologists grade diamonds from Internally Flawless (IF) as the highest quality to Included (I3).

Are laboratory grown diamonds flawless?
No, nearly all diamonds (mined or laboratory grown) have inclusions. Metallic inclusions can occur in laboratory grown diamonds. If an expert spots a trace of metal in a diamond, they can assume it is laboratory grown. While laboratory grown diamonds with defects do exist, Swarovski only uses high quality laboratory grown diamonds certified by the International Gemological Institute (IGI) according to the 4Cs to ensure that only the finest quality diamonds join the Swarovski Created Diamond collections.
Do laboratory grown diamonds get cloudy?
No, laboratory-grown diamonds do not get cloudy over time. They are 100% identical to diamonds with the same physical and chemical properties, and should not degrade or change appearance over time. Where poor quality diamond seeds have been used, some laboratory-grown diamonds contain obvious defects, such as color tinges from impurities in the diamond or crystal structure imperfections. The laboratory grown diamonds processed in Swarovski Created Diamonds jewelry are a very high quality standard and do not have unnatural, problematic characteristics.
How are laboratory grown diamonds certified and graded?
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。
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。
