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.

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.
Forme dei diamanti creati in laboratorio
Le collezioni Swarovski Created Diamonds presentano una gamma di diverse forme e tagli di diamanti creati in laboratorio. La forma di un diamante creato in laboratorio si riferisce al suo contorno o alla sua forma esterna quando viene osservato dall'alto. Il taglio è un indicatore di qualità, che riflette quanto bene la pietra sia stata sfaccettata e lucidata, nonché come angoli e proporzioni di ogni sfaccettatura siano stati studiati per interagire con la luce. Scegli una delle forme dei nostri Swarovski Created Diamonds per esprimere il tuo stile unico: ogni pietra, tagliata per esaltarne la brillantezza, aggiunge una luminosità straordinaria a qualsiasi look.
Parametri e fattori cromatici
Il colore del diamante più desiderabile è l'assenza totale di colore. Le pietre incolori sono molto ambite ma sono anche estremamente rare, mentre i diamanti di qualità inferiore possono avere una tonalità gialla o marrone. La scala del colore dei diamanti varia da D a Z e le collezioni Swarovski Created Diamonds utilizzano solo diamanti creati in laboratorio con una classificazione del colore da D a G.
Colorless
D-F
Near colorless
G-J
Slightly tinted

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.

Domande frequenti
FAQ sulle 4C del diamante
Che cosa sono le 4C?
Ogni diamante differisce lievemente dall’altro e presenta caratteristiche distintive. I nostri diamanti creati in laboratorio sono diamanti al 100% e, proprio come i diamanti estratti in miniera, vengono classificati secondo le 4C per la valutazione di qualità del diamante. Le 4C sono le abbreviazioni di color (colore), clarity (purezza), cut (taglio) e carat weight (peso in carati) e rappresentano gli standard universalmente riconosciuti per valutare la qualità di un diamante.
La purezza del diamante è importante?
A un maggiore grado di purezza corrispondono minori inclusioni o imperfezioni del diamante. Questo conferisce al diamante una qualità superiore rispetto ad un altro diamante di grado inferiore.
Qual è la massima purezza del diamante?
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?
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.
