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.

PRIVI DI DIFETTI INTERNI

Il massimo grado di purezza di un diamante è una pietra priva di difetti interni (IF) Questi diamanti sono incredibilmente rari e la maggior parte delle pietre, che vengano estratte in miniera o create in laboratorio, presenta inclusioni.

A occhio nudo

Sebbene quasi tutti i diamanti presentino imperfezioni, quelli classificati tra I.F. e SI 2 presentano inclusioni non visibili a occhio nudo, ma solo mediante ingrandimento.

Tipi di inclusione

I diversi tipi di inclusione di un diamante comprendono le inclusioni a fessura (“piuma”), puntiforme, a nuvola e metalliche. Le inclusioni metalliche si riscontrano esclusivamente nei diamanti creati in laboratorio.

UN’ILLUSIONE OTTICA

Inclusioni e imperfezioni possono influenzare il modo in cui un diamante riflette e assorbe la luce.

Diagramma di purezza del diamante

Scala e gradi di purezza del diamante

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.

Diagramma e simmetria del taglio del diamante

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

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.

MAXIMUM BRILLIANCE

A diamond cut shape that is perfectly symmetrical with aligned facets will reflect the light at the highest possible intensity, emitting a powerful shine.

DIAMOND CUT CHART

Diamond cuts are graded by the IGI on a scale of Excellent to Poor. An excellent cut requires technical mastery, artistry, and expertise.

EVERY FACET

Facet is the term used to describe each flat surface that makes up the surface of a diamond, each absorbing and dispersing the light differently.

The bEST CUT

While proportion, symmetry, and polish determine a diamond’s place on the diamond cut table, there is no best cut when it comes to a stone that sparks joy.

Colorless

D-F

Near colorless

G-J

Slightly tinted

K-M

Very light color

N-R

Light color

S-Z

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

Colorless stones are the most desirable in the world of diamonds and they are extremely rare. Swarovski Created Diamonds are evaluated against the standardized diamond color scale.

COLORLESS DIAMONDS

Truly colorless diamonds are extremely rare. Also known as ice white, D diamonds are also the most expensive diamond color to buy.

FIND YOUR SHADE

Finding a D diamond color isn’t always important when selecting your stone. A warm white might suit your individual style more than an ice white.

CONTROLLED ASSESSMENT

Each diamond’s color grade is assessed in a laboratory using controlled lighting, with the stone faced down, and with master samples used for comparison.

BLEMISHES

Laboratory grown diamonds do not include any intentional blemishes or the color defects that can come from the use of poorer quality carbon seeds.

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.

Diamond Carat Weight

Laboratory Grown Diamond Carat Scale

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?

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.

Les diamants de laboratoire ont-ils des imperfections ?

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. Swarovski ne commercialise pas de diamants aux défauts artificiels.

Qu’est-ce que le caratage ?

Un carat désigne l’unité de poids spécifiquement adaptée aux pierres précieuses, dont font partie nos diamants créés en laboratoire. 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 1/5ème 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.
