 What are the 4Cs of Diamonds?

Title:
Universally recognized, the 4Cs are a guiding light in the world of diamonds, helping to determine the quality and value of each stone. The 4Cs stand for colour, cut, carat, and clarity. The laboratory grown diamonds in the Swarovski Created Diamonds collections are graded against these 4Cs by IGI, the International Gemological Institute. The laboratory grown diamonds in these collections are of very fine quality: G+ in colour and VS+ in clarity.

What is 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 clarity grading.

Clarity Principles and Factors

Title:

The clarity of a lab grown diamond is judged by its flaws, which means the inclusions and blemishes that give it unique character and charm. Discover more about diamond clarity below.

INTERNALLY FLAWLESS

The highest possible clarity of diamond is an internally flawless (I.F.) stone. These are incredibly rare and most mined and laboratory grown stones have inclusions.

To The Naked Eye

While almost all diamonds are flawed, those graded between I.F. and SI 2 have inclusions that aren’t visible to the naked eye, only under magnification.

Types of Inclusion

The different types of diamond inclusion include feather, pinpoint, cloud, and metallic. Metallic inclusions are only found in lab created diamonds.

A TRICK OF THE LIGHT

Inclusions and blemishes can have an impact on the way a diamond reflects and absorbs the light.

Diamond Clarity Chart

Diamond clarity scale and grades

Subtitle:
The diamond clarity scale runs from I.F. to I 3 and is based on the number of inclusions and blemishes found in each stone. Diamond clarity grades are determined under standard viewing conditions with 10x magnification; I.F. is used to represent an internally flawless diamond, while at the other end of the diamond clarity chart, I 3 stands for the inclusion of a visible blemish. Truly flawless diamonds are extremely rare – almost all stones, including laboratory grown diamonds, have inclusions of some kind or other.
diamond cut chart and symmetry

What is 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 stone its personality, and perfecting the proportions, symmetry, and precision-cut angles of lab made diamonds gives them their brilliant shine.

Cut Principles and Factors

Title:

The quality of how a lab grown diamond is cut is based on its proportions, symmetry, and polish. An expert cut creates a multitude of facets, absorbing and reflecting the light so the stone shimmers from every angle.

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.

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 lab grown diamonds in its collections, meaning they range from colorless to nearly colorless diamonds (D-G).

Color Principles and Factors

Title:
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

Title:

Lab 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.

Preguntas frecuentes

Preguntas frecuentes de las 4 C del diamante

¿Qué son las 4 C?

Cada diamante se diferencia un poco del resto y tiene sus propias características distintivas. Los diamantes creados en laboratorio son diamantes 100 %. Como los diamantes extraídos, nuestros diamantes creados en laboratorio se evalúan conforme a las 4 C de calificación de diamantes. Las 4C son color, pureza, talla y peso en quilates, que son los estándares aceptados internacionalmente para valorar la calidad de un diamante.

¿La pureza del diamante es importante?

Cuando mayor sea la calificación de pureza, menos inclusiones e imperfecciones tendrá el diamante, lo que hará que tenga más valor que uno de menor calificación.

¿Cuál es la pureza máxima del diamante?

La pureza del diamante es la medida de pureza de la piedra que se califica por la visibilidad de dos características: las inclusiones y las imperfecciones. 
Para valorar la pureza, el diamante se observa bajo un aumento de 10x. El número y la naturaleza de las características externas (imperfecciones) e internas (inclusiones), así como el tamaño y la posición, determinan su calificación. 
Los gemólogos califican el diamante desde Internamente perfecto (IF), que es el de máxima calidad, hasta Con inclusiones (I3).

¿Los diamantes creados en laboratorio son perfectos?

No, prácticamente todos los diamantes (extraídos o creados en laboratorio) tienen inclusiones. Los diamantes creados en laboratorio pueden contener inclusiones metálicas. Si un experto identifica una traza de metal en un diamante, sobreentenderá que se trata de un diamante creado en laboratorio. Los diamantes creados en laboratorio pueden tener defectos, pero Swarovski solo utiliza diamantes creados en laboratorio de la máxima calidad certificados por el Instituto Gemológico Internacional (IGI) según las 4 C, con el fin de garantizar que solo se incluyan los diamantes de más calidad en las colecciones Swarovski Created Diamond.

¿Los diamantes creados en laboratorio se vuelven opacos con el tiempo?

No, los diamantes creados en laboratorio no se opacan con el paso del tiempo. Son 100 % iguales que los diamantes con las mismas propiedades físicas y químicas, de manera que no deben degradarse ni cambiar de aspecto con el paso del tiempo. Si se utilizan semillas de mala calidad, algunos diamantes creados en laboratorio pueden contener defectos evidentes, como trazas de color por impurezas o una estructura del cristal imperfecta. Los diamantes creados en laboratorio desarrollados en la joyería Swarovski Created Diamonds responden a un estándar de la más alta calidad y no tienen características no naturales o que puedan causar problemas.

¿Cómo se califican y se certifican los diamantes creados en laboratorio?

Los diamantes creados en laboratorio procesados en la joyería de Swarovski Created Diamonds se seleccionan manualmente y los examinan gemólogos expertos para garantizar que cumplan con los más altos estándares de calidad.  Cada pieza de joyería de las colecciones Galaxy y Eternity se acompaña de un informe de laboratorio digital emitido por el Instituto Gemológico Internacional (IGI). 

¿Qué son las facetas de un diamante?

Las facetas de un diamante son cada superficie facetada que crea la forma del diamante. Un diamante tiene varias facetas que absorben y reflejan la luz.

¿Cómo se determina la calidad de la talla de un diamante?

Generalmente, pensamos que la talla de un diamante hace referencia a su forma (redondo, ovalado, en corazón, marquesa, pera). Sin embargo, la talla del diamante significa lo bien que interactúan las facetas del diamante con la luz.  La talla de un diamante es la medida de calidad de la forma, la geometría y el acabado del diamante.  Los diamantes redondos brillantes reciben una calificación de talla oficial en una escala que va desde Ideal (el máximo) a Pobre.  Swarovski se compromete con la calidad de la talla para garantizar que nuestros diamantes creados en laboratorio tienen un brillo y un reflejo de la luz inmejorables.

¿Cuál es la mejor talla de diamante?

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?

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.
