¿Qué son las 4 C del diamante?

Las 4 C internacionalmente reconocidas son la referencia en el mundo de los diamantes y permiten establecer la calidad y el valor de cada piedra según su color, talla, peso y pureza. Los diamantes creados en laboratorio de las colecciones Swarovski Created Diamonds se han sometido a las 4 C por el Instituto Gemológico Internacional (IGI). Los diamantes creados en laboratorio de estas colecciones son de la máxima calidad: G+ en color y VS+ en pureza.

¿Qué es la pureza del diamante?

La pureza del diamante es una medida de pureza de la piedra que se categoriza por la visibilidad de dos características: inclusiones e imperfecciones. Para valorar la pureza, el diamante se revisa bajo un aumento de 10x. El número y la naturaleza de las características externas (imperfecciones) e internas (inclusiones), así como su medida y la posición, determinan la calificación de la pureza.

Principios y factores de la pureza

La pureza de un diamante creado en laboratorio se establece por sus defectos, que son las inclusiones e imperfecciones que le dan su carácter y encanto único. Más abajo, descubre más sobre la pureza del diamante.

INTERIORMENTE PERFECTO

La mayor pureza de diamante posible la tiene una piedra internamente perfecta (IF). Este tipo de piedras son muy escasas y la mayoría de diamantes creados en laboratorio y en la propia tierra tienen inclusiones.

Para el ojo humano

La mayoría de los diamantes tienen algún defecto, pero los calificados entre internamente perfectos (IF) y con inclusiones pequeñas (SI 2) tienen inclusiones no perceptibles a simple vista, ya que solo pueden apreciarse bajo aumento.

Tipos de inclusión

Los diferentes tipos de inclusión de un diamante son plumas, puntos, nubes y las metálicas. Las inclusiones metálicas solo se encuentran en diamantes creados en laboratorio.

UN TRUCO DE LA LUZ

Las inclusiones y las imperfecciones pueden afectar a la manera como el diamante refleja y absorbe la luz.

Grados y escala de pureza del diamante

La escala de pureza del diamante va de IF a I 3 y se basa en el número de inclusiones e imperfecciones que contiene cada piedra. El grado de pureza de un diamante se establece bajo condiciones de visualización estándar con un aumento de 10x. El IF representa un diamante interiormente perfecto, mientras que en el otro extremo de la gráfica de pureza de un diamante, el I 3 indica la inclusión de una imperfección visible. Los diamantes totalmente perfectos son muy escasos. Prácticamente todas las piedras, incluidos los diamantes creados en laboratorio, tienen algún tipo de inclusión.

gráfico y simetría de talla del diamante

¿Qué es la talla del diamante?

La talla hace referencia a cómo las facetas del diamante interactúan con la luz y revelan su fuego interior. La talla es lo que da la personalidad a cada piedra, y la perfección de las proporciones, la simetría y los ángulos de corte preciso de los diamantes creados en laboratorio les aportan su brillo propio.

Principios y factores de la talla

La calidad de la talla de un diamante creado en laboratorio se basa en las proporciones, la simetría y el pulido. Una talla experta crea muchas facetas que absorben y reflejan la luz, lo que permite que una piedra brille desde cada ángulo.

MASSIMA BRILLANTEZZA

Una forma tagliata a diamante perfettamente simmetrica con sfaccettature allineate rifletterà la luce con la massima intensità possibile, generando un'intensa lucentezza.

DIAGRAMMA DEI TAGLI DEL DIAMANTE

I tagli dei diamanti sono classificati dal IGI su una scala da Eccellente (Excellent) a Scarso (Poor). Un taglio eccellente richiede maestria tecnica, abilità artistica e competenza.

MOLTEPLICI SFACCETTATURE

Sfaccettatura è il termine utilizzato per descrivere ogni superficie piana che costituisce la superficie di un diamante. Ogni sfaccettatura assorbe e disperde la luce in modo diverso.

IL TAGLIO MIGLIORE

Se proporzione, simmetria e lucidatura determinano il posizionamento di un diamante nella classifica dei tagli, il taglio migliore è sempre quello che regala gioia.

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).

Parametri e fattori cromatici

Le pietre incolori sono le più richieste nel mondo dei diamanti e sono estremamente rare. Gli Swarovski Created Diamonds vengono valutati secondo la scala standardizzata per il colore dei diamanti.

DIAMANTI INCOLORI

I diamanti veramente incolori sono estremamente rari. Noti anche come di tinta bianco ghiaccio, i diamanti di colore D sono i più costosi.

TROVA LA GRADAZIONE ADATTA A TE

Trovare un diamante di colore D non è sempre determinante per la scelta di una pietra. Un bianco di un tono più caldo potrebbe adattarsi meglio al tuo stile personale rispetto ad un bianco ghiaccio.

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?

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.

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?

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.
