Che cosa sono le 4C dei diamanti?
Title:Standard universalmente riconosciuto, le 4C rappresentano la stella polare nell’universo dei diamanti e aiutano a determinare la qualità e il valore di ogni pietra. Le 4C sono l’abbreviazione di color (colore), cut (taglio), carat (peso in carati) e clarity (purezza). I diamanti creati in laboratorio delle collezioni Swarovski Created Diamonds vengono classificati in base a queste 4C dall’IGI, l’Istituto Gemmologico Internazionale. I diamanti di queste collezioni sono di qualità molto pregiata: G+ per colore e VS+ per purezza.
Che cos’è la purezza del diamante?
La purezza del diamante è una valutazione della perfezione della pietra classificata in base alla visibilità di due tipi di caratteristiche: inclusioni e imperfezioni. Per valutarne la purezza, il diamante viene esaminato con una lente di ingrandimento 10x. Il numero e la natura delle caratteristiche esterne (imperfezioni) e interne (inclusioni), nonché la loro dimensione e posizione, determinano il grado di purezza.
Parametri e fattori di purezza

La purezza di un diamante creato in laboratorio dipende dai suoi difetti, ovvero dalle inclusioni e dalle imperfezioni che gli conferiscono una personalità ed un fascino unici. Scopri di più sulla purezza del diamante qui di seguito.

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.

Diamond color scale and chart
Diamond coloring is rated on a scale from D to Z, with D clear ice white with no hint of yellow, while those rated Z are shades of yellow and brown. Each letter range on the chart denotes a shade of stone, with those rated D to F appearing colorless, through to S to Z appearing in shades of light yellow or brown. Swarovski only accepts the finest laboratory grown diamonds in its collections, meaning they range from colorless to nearly colorless diamonds (D-G).
Color Principles and Factors

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?
Lorsqu’on parle de taille, on pense souvent à la silhouette de la pierre (ronde, cœur, ovale, marquise ou poire), alors qu’elle fait référence à la façon dont ses facettes interagissent avec la lumière. En réalité, la taille correspond à la mesure de la qualité des proportions géométriques, de la forme et de la finition du diamant. Les brillants seront notés sur une échelle allant de Idéal à Médiocre. Swarovski ne fait aucun compromis sur la qualité de la taille afin que chaque diamant de synthèse diffuse un maximum de lumière et d’éclat.
Quelle est la meilleure taille de diamant ?
La taille fait référence aux différentes manières dont les facettes interagissent avec la lumière pour révéler le feu intérieur du diamant. C’est elle qui confère au diamant sa personnalité, tandis que l’attention apportée aux proportions, à la symétrie et aux facettes de nos Swarovski Created Diamonds sublimera leur brillance. La taille parfaite offre le juste équilibre entre largeur et profondeur, pour créer une symétrie : ni trop plat, ni trop profond. L’objectif étant de créer le point de réfraction parfait pour que la lumière circule à l’intérieur du diamant et soit réfléchie tout en mettant en valeur son éclat.
Comment déterminer la couleur d’un diamant ?
La couleur fait référence à la teinte naturelle du diamant blanc. L’usage est de comparer la couleur de chaque diamant avec un échantillon de référence, puis d’attribuer à celui-ci une lettre, allant de D (incolore) à Z (jaune pâle).
Plus le diamant est incolore, meilleure sera jugée la qualité.
Plus le diamant est incolore, meilleure sera jugée la qualité.
Les diamants de synthèse ont-ils des imperfections ?
Lorsque le grain de carbone utilisé est de qualité inférieure, certains diamants de synthèse peuvent contenir des défauts apparents, comme des problèmes de tonalités, des impuretés ou des altérations. Swarovski ne commercialise pas de diamants de synthèse qui présentent des défauts.
Qu’est-ce que le caratage ?
Un carat désigne l’unité de poids spécifiquement adaptée aux pierres précieuses, dont font partie nos diamants de synthèse. Un diamant pourra posséder un caratage plus élevé sans nécessairement être plus volumineux. De la même façon, le calibre de deux diamants de caratages identiques pourra varier selon la profondeur de la taille. Un carat pèse un 1/5e de gramme et se divise en centièmes.
Qu’est-ce que le caratage du diamant ? A-t-il une importance et comment le mesurer ?
Le carat est l’unité de mesure standard du diamant et le premier critère d’évaluation pour déterminer la valeur de celui-ci. Le caratage mesure le poids du diamant. Chaque carat se divise en centièmes, permettant une mesure des plus précises. Un diamant de moins d’un carat sera exprimé en centièmes. Plus le diamant est gros, plus il contiendra de carats. Mais savoir si cela le rend précieux à vos yeux reste une question très personnelle.
Un caratage élevé est-il préférable ?
C’est une question très personnelle. Si vous souhaitez acquérir un gros diamant, le caratage aura alors son importance car du poids dépend la taille de celui-ci.
