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.
Formas dos diamantes criados em laboratório
As coleções de Swarovski Created Diamonds apresentam uma gama de diferentes formatos e cortes de diamantes criados em laboratório. A forma de um diamante criado em laboratório refere-se ao seu contorno ou forma externa quando visto de cima. O corte é um indicador de qualidade, refletindo quão bem a pedra foi facetada e polida, bem como a forma como os ângulos e proporções de cada faceta foram trabalhados para interagir com a luz. Escolha uma das formas de Swarovski Created Diamonds para refletir o seu estilo individual e, como cada pedra é cortada para o brilho, ela adicionará luminosidade a qualquer look.
Princípios e fatores de cor
A cor de diamante desejável é a ausência total de cor. Pedras incolores são altamente valorizadas, mas também são extremamente raras, enquanto diamantes de menor qualidade podem ter um tom amarelado ou acastanhado. A escala de cor de diamante varia de D a Z e as coleções Swarovski Created Diamonds utilizam apenas diamantes criados em laboratório com uma classificação de cor de D-G.

Escala de cor dos diamantes
A cor do diamante é classificada numa escala de D a Z. D a F são usados para denotar pedras incolores, enquanto aquelas nas categorias de S a Z aparecem em tons de amarelo claro ou castanho. As joias Swarovski Created Diamonds só usam os melhores diamantes criados em laboratório, o que significa que variam de diamantes incolores a quase incolores (D-G).
O que é o peso em quilates de um diamante?
Um quilate é uma unidade de peso usada para medir pedras preciosas, incluindo diamantes criados em laboratório. Ao comparar diamantes, cada diamante pode ter um peso em quilates mais elevado sem parecer maior, e dois diamantes com o mesmo peso em quilates podem variar em tamanho se um for cortado mais profundamente do que o outro. Um quilate pesa 1/5 de um grama e é dividido em 100 pontos.

Tabela de peso do diamante em quilates
Title:Escala de quilates de diamantes criados em laboratório
Subtitle:
Os quilates são uma unidade de medida padrão internacional para o peso de um diamante. É derivada da palavra “alfarroba”, uma semente que era usada como referência de peso para diamantes por comerciantes no mundo antigo. Um quilate é igual a 200 miligramas. Assim, um diamante de 5 quilates pesa um grama. O quilate do diamante não equivale ao tamanho de uma pedra, refere-se simplesmente ao seu peso, e os diamantes tendem a ser mais caros à medida que o seu peso em quilates aumenta.
Qualidade garantida
Cada diamante criado em laboratório, inserido nas peças de joalheria da Swarovski Created Diamonds, é avaliado e certificado pelo IGI (Instituto Gemológico Internacional), usando os universalmente reconhecidos 4Cs. O corte, a pureza, a cor e o quilate de cada pedra determinam a sua qualidade e valor. A Swarovski utiliza apenas diamantes criados em laboratório de alta qualidade, classificados como G+ em cor e VS+ em pureza.

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.
