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.
La clarté
La clarté du diamant définit la pureté de celui-ci. La pierre est évaluée en fonction de deux critères visuels : les inclusions et les imperfections. Pour ce faire, le gemmologue a recours à une loupe de grossissement 10x. Le nombre et la nature des éléments externes (imperfections) et internes (inclusions), ainsi que leur taille et leur position déterminent le degré de clarté.

Reinheitsskala für Diamanten
Title:Reinheitsskala für Diamanten und Reinheitsgrade
Subtitle:
Die Reinheitsgradskala für Diamanten reicht von I.F. bis I 3 und wird an der Anzahl der Einschlüsse und Mängel ausgerichtet, die der Diamant aufweist. Der Reinheitsgrad eines Diamanten wird unter Standardbedingungen bewertet, mit einer 10-fachen Vergrößerung. I.F. steht für makellos und auf der anderen Ende der Reinheitsskala für Diamanten I 3 einen Einschluss mit einem sichtbaren Mangel bezeichnet. Wahrhaftig makellose Diamanten sind sehr selten – fast alle Steine, einschließlich im Labor gezüchtete Diamanten, weisen Einschlüsse auf.
Was ist Diamantschliff?
Der Schliff bezieht sich auf die Interaktion der verschiedenen Facetten eines Diamanten mit Licht, um sein inneres Feuer zu entfachen. Es ist der Schliff, der jedem einzelnen Stein seine Persönlichkeit verleiht. Er perfektioniert die Proportionen, die Symmetrie und die Winkel. Der Präzisionsschliff von im Labor gezüchteten Diamanten, verleiht ihnen ihre unverkennbare Brillanz.
Schliffprinzipien und -faktoren
Title:
Die Qualität des Schliffs eines im Labor gezüchteten Diamanten basiert auf seinen Proportionen, der Symmetrie und Politur. Bei einem professionellen Schliff entstehen zahlreiche Facetten, die das Licht gleichzeitig absorbieren und reflektieren und den Edelstein von jeder Seite hell strahlen lassen.

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.

Foire aux questions
Les 4C du diamant - FAQ
Que signifient les 4C ?
Aucun diamant ne ressemble à un autre. Chaque pierre possède ses caractéristiques propres. Tout comme les diamants naturels, nos diamants créés en laboratoire sont évalués selon quatre critères appelés 4C. Reconnus dans le monde entier par l’industrie diamantaire, ces 4C interviennent dans le contrôle qualité du diamant et se réfèrent à la taille (cut), la clarté (clarity), la couleur (color) et le caratage (carat).
La clarté du diamant est-elle importante ?
Plus le degré de clarté est élevé, plus le diamant aura de la valeur, car il contiendra moins d’inclusions et d’imperfections.
Quel est le degré de clarté le plus élevé du diamant ?
La clarté dépend de la pureté de la pierre qui, elle-même, repose sur deux critères visuels : les inclusions et les imperfections.
Afin d’évaluer sa clarté, le diamant est inspecté à l’aide d’une loupe de grossissement 10x. Le nombre et la nature des éléments externes (imperfections) et internes (inclusions), ainsi que leur taille et leur position déterminent le degré de clarté.
Les pierres sont classées par les gemmologues de la meilleure note, IF (sans défaut interne), à la moins bonne, I3 (Inclusions).

Les pierres sont classées par les gemmologues de la meilleure note, IF (sans défaut interne), à la moins bonne, I3 (Inclusions).
Les diamants de laboratoire sont-ils sans défaut ?
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?
Color refers to the natural tint inherent in white diamonds. The industry standard for grading color is to evaluate each diamond against a master set then assign a letter grade from D (colorless) to Z (light yellow).
The closer the diamond is to being colorless, the higher its quality.
The closer the diamond is to being colorless, the higher its quality.
Do laboratory created diamonds have blemishes?
Where poor quality diamond seeds have been used, some laboratory-grown diamonds contain obvious defects, such as color tinges from impurities or structural imperfections. Swarovski does not sell laboratory grown diamonds with unnatural, problematic characteristics.
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.
What is the carat weight of a diamond, how is it measured and how important is it?
Le carat est l’unité de mesure standard du diamant et le premier critère d’évaluation pour déterminer la valeur de celui-ci. Le caratage mesure le poids du diamant. Chaque carat se divise en centièmes, permettant une mesure des plus précises. Un diamant de moins d’un carat sera exprimé en centièmes. Plus le diamant est gros, plus il contiendra de carats. Mais savoir si cela le rend précieux à vos yeux reste une question très personnelle.
Un caratage élevé est-il préférable ?
C’est une question très personnelle. Si vous souhaitez acquérir un gros diamant, le caratage aura alors son importance car du poids dépend la taille de celui-ci.
