Clarté : principes et facteurs
La pureté d’un diamant de synthèse est déterminée par ses imperfections. Chaque pierre a des inclusions et des défauts qui lui confèrent un caractère et un charme uniques, dont beaucoup ne sont visibles qu’au microscope. L’échelle de pureté des diamants va de Parfait (FL) à Inclusions (I3). À l’extrémité inférieure de l’échelle, les inclusions peuvent affecter la transparence, la brillance et la durabilité du diamant.

Tableau de pureté des diamants de synthèse
Title:Échelle d’évaluation de la clarté du diamant
Subtitle:
L’échelle de pureté des diamants est utilisée pour indiquer la pureté d’une pierre basée sur deux caractéristiques naturelles : les inclusions et les imperfections. Le nombre, la nature, la taille et l’emplacement des caractéristiques externes (imperfections) et internes (inclusions) déterminent la note de pureté d’un diamant. Les grades de pureté des diamants sont déterminés dans des conditions d’observation standard avec un grossissement de 10x. IF est utilisé pour signifier un diamant sans défauts internes tandis que I3 représente un diamant avec des inclusions évidentes et visibles.
Qu’est-ce que la taille ?
La qualité de la taille dépend du savoir-faire. Le terme fait référence à la façon dont chaque facette d’un diamant interagit avec la lumière et révèle son éclat intérieur. La taille donne à chaque pierre sa propre personnalité, ses proportions parfaites, sa symétrie. Chaque angle taillé avec précision confère à nos diamants de synthèse une brillance éclatante.
Taille : principes et facteurs
La qualité d’un diamant de synthèse dépend de ses proportions, de sa symétrie et de son polissage. Une taille experte permet d’obtenir plusieurs facettes parfaitement taillées qui absorbent et reflètent la lumière, de sorte que la pierre scintille sous tous les angles. Lors de l’évaluation de la taille, les experts considèrent l’apparence du diamant vue de dessus, son design et son savoir-faire.
Formes des diamants de synthèse
Les collections de Swarovski Created Diamonds présentent une gamme de différentes formes et tailles de diamants de synthèse. La forme d’un diamant de synthèse se réfère à son contour ou à sa forme externe, vue de dessus. La taille est un indicateur de qualité, reflétant la qualité du travail de facettage et de polissage, ainsi que la manière dont les angles et proportions de chaque facette ont été conçus pour interagir avec la lumière. Choisissez l’une de nos formes de Swarovski Created Diamonds pour refléter votre style individuel. Chaque pierre est taillée pour offrir la brillance, elle ajoutera de la luminosité à toutes vos tenues.
Couleur : principes et facteurs
La couleur la plus désirable pour un diamant est l’absence totale de couleur. Les pierres incolores sont très prisées mais elles sont également extrêmement rares, tandis que les diamants de moindre qualité peuvent avoir une teinte jaune ou marron. L’échelle de couleur des diamants va de D à Z et les collections Swarovski Created Diamonds n’utilisent que des diamants de synthèse ayant une classification de couleur de D à G.

Diamond color scale
Diamond color is rated on a scale from D to Z. D to F are used to denote colorless stones, while those in the S to Z categories appear in shades of light yellow or brown. Swarovski Created Diamonds jewelry only uses the finest laboratory grown diamonds, meaning they range from colorless to near colorless (D-G).
What is Diamond Carat Weight?
A carat is a unit of weight used to measure precious stones including laboratory grown diamonds. When comparing diamonds, one can have a higher carat without appearing larger, and two diamonds with the same carat weight can vary in size if one is cut deeper than the other. One carat weighs one-fifth of a gram and can be divided into 100 points.

Diamond Carat Weight Chart
Title:Laboratory grown diamond carat scale
Subtitle:
Carats are the international standard unit of measurement for the weight of a diamond. It derives from the word ‘carob’, a seed that was used as a diamond weight reference for traders in the ancient world. One carat is equal to 200 milligrams so a five carat diamond will weigh one gram. Diamond carat doesn’t equate to the size of a stone, it simply refers to how much it weighs, and diamonds usually become more expensive as their carat weight increases.
Quality Assured
Every laboratory grown diamond set in Swarovski Created Diamonds fine jewelry is assessed and certified by the IGI (International Gemological Institute), using the universally recognized 4Cs. The cut, clarity, color, and carat of each stone determines its quality and worth. Swarovski only uses high quality laboratory grown diamonds rated G+ in color and VS+ in clarity.

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).

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?
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?
Carat weight it the standard weight unit for diamonds, and the first step in the grading process. Diamond carat weight is the measurement of how much the diamond weighs. Each carat can be subdivided into 100 “points.” This allows precise measurements to the hundredth decimal place. The weight of a diamond smaller than one carat may be described by its “points” alone. The larger the diamond is, the more carats it will be, but only you can decide how important that is to you.
Is it better to have a higher carat diamond?
This is an entirely personal question. If you are looking for a larger diamond, you should look for a higher carat, as this indicates the weight and therefore the size of the diamond.
