Que signifie 4C ?
Title:
Reconnus dans le monde entier, les 4C sont la référence universelle dans le monde diamantaire pour évaluer la qualité et la valeur d’une pierre, selon quatre critères : la taille (Cut), la pureté (Clarity), la couleur (Color) et le poids (Carat). Les diamants de synthèse des collections Swarovski Created Diamonds® sont également évalués sur la base des 4C par l’IGI (International Gemological Institute). Ces diamants de synthèse se distinguent par leur qualité exceptionnelle : une couleur classée G+ et une pureté VS+.
La pureté
La pureté du diamant est une mesure de la clarté de la pierre notée selon la présence de deux caractéristiques : inclusions et imperfections.
Le diamant est inspecté avec une loupe x10 pour évaluer sa pureté.
Le nombre et la nature de l’extérieur (imperfections) et les caractéristiques internes (inclusions), ainsi que leur taille et leur position, déterminent la note.
Pureté : principes et facteurs

Diagramma di purezza del diamante
Title:Scala e gradi di purezza del diamante
Subtitle:
La scala di purezza del diamante va da I.F a I3 e si basa sul numero di inclusioni e imperfezioni riscontrate in ogni pietra. I gradi di purezza del diamante sono determinati in condizioni di visualizzazione standard con lente di ingrandimento 10x. La categoria I.F indica un diamante privo di inclusioni interne mentre, all’altra estremità del diagramma di purezza del diamante, I3 indica l’inclusione di un’imperfezione visibile. I diamanti completamente privi di inclusioni sono estremamente rari. Quasi tutte le pietre, compresi i diamanti creati in laboratorio, presentano inclusioni di qualche tipo.
Che cos’è il taglio del diamante?
Il taglio si riferisce al modo in cui le sfaccettature del diamante interagiscono con la luce per rivelarne il fulgore interiore. Il taglio conferisce ad ogni pietra una personalità unica, mentre il perfezionamento delle proporzioni, la simmetria e le angolazioni tagliate con precisione dei diamanti creati in laboratorio conferiscono loro una brillante lucentezza.
Parametri e fattori di taglio
Title:
La qualità del taglio di un diamante creato in laboratorio è determinata dalle sue proporzioni, dalla sua simmetria e dalla sua lucidatura. Un taglio a regola d'arte crea molteplici sfaccettature che assorbono e riflettono la luce e fanno brillare la da ogni angolazione.

Scala e diagramma di colore del diamante
La colorazione dei diamanti è valutata su una scala da D a Z, in cui D indica un colore bianco ghiaccio limpido senza alcun accenno di giallo, mentre i diamanti classificati con Z presentano sfumature di giallo e marrone. Ogni lettera sul diagramma definisce una sfumatura della pietra: quelle classificate da D a F appaiono incolori, mentre quelle classificate da S a Z presentano tonalità giallo chiaro o marrone. Swarovski include nelle sue collezioni esclusivamente i diamanti creati in laboratorio della massima qualità, ovvero diamanti classificati da incolori a quasi incolori (fascia D-G).

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?
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.
