Que signifie 4C ?
Title:
Reconnus dans le monde entier, les 4C sont une référence dans le monde diamantaire pour évaluer la qualité et la valeur d’une pierre, selon quatre critères : la taille (cut), la clarté (clarity), la couleur (color) et le caratage (carat). Les diamants créés en laboratoire des collections Swarovski Created Diamonds sont également évalués en fonction des 4C par l’IGI (International Gemological Institute). Les diamants créés en laboratoire se distinguent par leur excellente qualité : G+ pour la couleur et VS+ pour la clarté.
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.

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?
The laboratory grown diamonds processed in Swarovski Created Diamonds jewelry are hand-selected and examined by experienced gemologists to ensure they fulfill our high quality standards. Every piece of jewelry in the Galaxy and Eternity collections is accompanied with a digital laboratory report from the International Gemological Institute (IGI).
What are diamond facets?
Diamond facets refer to each flat surface that creates the shape of a diamond. Every diamond possesses multiple facets that enable it to absorb and reflect light.
How is diamond cut quality determined?
We often think of a diamond’s cut as shape (round, heart, oval, marquise, pear), but what diamond cut actually does mean is how well a diamond’s facets interact with light. The cut of a diamond is the measure of the quality of the shape, geometry and finish of the diamond. Round brilliant diamonds receive a formal cut grade on a scale from Ideal (the best) to Poor. Swarovski is uncompromising on cut quality to ensure all of our laboratory grown diamonds have optimal light performance and sparkle.
What is the best 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 diamond its personality, and perfecting laboratory grown diamonds proportions, symmetry, and precision-cut angles of Swarovski Created Diamonds gives them their brilliant shine. The best cut has a balance between the width and depth to create symmetry, neither to shallow nor to deep. Creating the perfect refraction point for light through the diamond, reflecting it within the diamond and highlighting its polished brightness.
How is a diamond’s color determined?
Farbe bezeichnet bei weißen Diamanten den natürlichen Farbton. Der Branchenstandard für die Einstufung der Farbe wird verwendet, um jeden Diamanten basierend auf einer Referenzskala zu bewerten, um ihm anschließend einen Buchstaben von D (farblos) bis Z (hellgelb) zuzuweisen.
Je mehr sich der Diamant der Stufe farblos nähert, desto höher ist die Qualität.
Je mehr sich der Diamant der Stufe farblos nähert, desto höher ist die Qualität.
Weisen im Labor gezüchtete Diamanten Mängel auf?
Wurden minderwertige Diamantkeime verwendet, dann weisen manche im Labor gezüchteten Diamanten offensichtliche Mängel auf, wie Farbbeeinträchtigungen durch Unreinheiten oder strukturelle Fehler. Swarovski verkauft keine im Labor gezüchteten Diamanten mit unnatürlichen, problematischen Eigenschaften.
Was ist das Karatgewicht eines Diamanten?
Ein Karat ist eine Gewichtseinheit, die speziell dafür verwendet wird, um Edelsteine einzustufen, dies gilt auch für im Labor gezüchtete Diamanten. Ein Diamant kann ein höheres Karatgewicht haben, ohne größer als ein anderer mit einem geringeren Karatgewicht auszusehen. Zwei Diamanten mit demselben Karatgewicht können unterschiedlich groß sein, wenn einer davon tiefer geschliffen ist. Ein Karat wiegt 1/5 eines Gramms und wird in 100 Punkte aufgeteilt.
Was ist das Karatgewicht, wie wird es erfasst und wie wichtig ist es?
Das Karatgewicht ist die Standard-Gewichtseinheit für Diamanten und ist der erste Schritt des Evaluierungsverfahrens. Das Karatgewicht eines Diamanten gibt an, wie viel ein Diamant wiegt. Jedes Karat kann in 100 „Punkte“ unterteilt werden. Dies ermöglicht eine genaue Erfassung bis auf Hundertstel. Ein Diamant, der weniger wiegt als ein Karat, kann ausschließlich mit „Punkten“ eingestuft werden. Je größer ein Diamant ist, desto mehr Karat weist er in der Regel auf, doch nur Sie können entscheiden, wie wichtig Ihnen dieser Aspekt ist.
Ist ein hochkarätiger Diamant besser?
Das ist eine sehr persönliche Frage. Wenn Sie auf der Suche nach einem größeren Diamanten sind, dann sollten nach mehr Karat Ausschau halten, denn dies ist ein Hinweis auf das Gewicht und somit auf die Größe des Diamanten.
