Clarity Principles and Factors
The clarity of a laboratory grown diamond is determined by its flaws. Every stone has inclusions and blemishes that give it unique character and charm, many of which are only visible under a microscope. The diamond clarity scale ranges from Flawless (FL) to Included (I3). At the lower end of the scale, inclusions may affect the diamond’s transparency, brilliance, and durability.

Laboratory Grown Diamond Clarity Chart
Title:Diamond clarity scale and grades
Subtitle:
The diamond clarity scale is used to indicate the purity of a stone based on two naturally occurring characteristics: inclusions and blemishes. The number, nature, size, and location of external (blemishes) and internal (inclusions) features determine a diamond’s clarity rating. Diamond clarity grades are decided under standard viewing conditions with 10x magnification. IF is used to signify an internally flawless diamond while I3 stands for a diamond with obvious and visible inclusions.
What is Diamond Cut?
Cut quality depends on craftsmanship. The term refers to the way each diamond’s facets interact with the light and reveal its internal fire. Cut gives each stone its distinct personality, and perfecting the proportions, symmetry, and precise angles of laboratory grown diamonds ensures they are cut for maximum brilliance.
Cut Principles and Factors
The quality of a laboratory grown diamond cut is based on its proportions, symmetry, and polish. An expert cut results in several perfectly crafted facets that absorb and reflect the light so the stone scintillates from every angle. When assessing cut, graders consider the diamond’s face-up appearance, design, and craftsmanship.
Laboratory Grown Diamond Shapes
Swarovski Created Diamonds collections feature a range of different laboratory grown diamond shapes and cuts. The shape of a laboratory grown diamond refers to its outline or external form when viewed from above. Cut is a marker of quality, reflecting how well the stone has been faceted and polished as well as how the angles and proportions of each facet have been crafted to interact with the light. Choose one of our Swarovski Created Diamonds shapes to reflect your individual style and, as each stone is cut for brilliance, it will add luminosity to any look.
Color Principles and Factors
The most desirable diamond color is no color at all. Colorless stones are highly prized but they are also extremely rare, whereas lower quality diamonds can have a yellow or brown tone. The diamond color scale ranges from D to Z and Swarovski Created Diamonds collections only use laboratory grown diamonds with a color rating of D-G.
Colorless
D-F
Near colorless
G-J
Slightly tinted
K-M
Very light color
N-R
Light color
S-Z
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.

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 ?
Non, presque tous les diamants (extraits ou créés en laboratoire) contiennent des inclusions. Les inclusions métalliques ne concernent que les diamants de laboratoire. Si une trace de métal est détectée, on peut ainsi supposer qu’il s’agit d’un diamant de laboratoire. Bien que les diamants créés en laboratoire possèdent des défauts, Swarovski n’utilise que les pierres de la plus haute qualité dans ses collections Swarovski Created Diamond, certifiées par l’IGI (International Gemological Institute) et les 4C.
Les diamants de laboratoire peuvent-ils perdre leur éclat ?
Non, les diamants de laboratoire ne perdent rien de leur éclat avec le temps. Strictement identiques aux diamants naturels, ils sont dotés des mêmes caractéristiques physiques et chimiques. Leur apparence ne s’altère pas avec le temps. Lorsque le grain de carbone utilisé est de qualité inférieure, certains diamants peuvent contenir des défauts apparents, comme des problèmes de tonalités, des impuretés ou des altérations. Les bijoux Swarovski Created Diamonds ne contiennent aucun diamant aux défauts artificiels.
Comment se passe la certification et l’évaluation des diamants créés en laboratoire ?
Les diamants de laboratoire servant à la création des bijoux Swarovski Created Diamonds sont sélectionnés à la main et examinés par des experts gemmologues qui s’assurent de leur conformité aux normes de la plus haute qualité. Chaque pièce des collections Galaxy et Eternity est accompagnée d’un certificat numérique émis par l’IGI (International Gemological Institute).
Qu’appelle-t-on facette du diamant ?
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.
