 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.

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 colour scale and chart

Diamond colouring 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 colourless, 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 colourless to nearly colourless diamonds (D-G)

Colour Principles and Factors

Title:
Colourless stones are the most desirable in the world of diamonds and they are extremely rare. Swarovski Created Diamonds are evaluated against the standardized diamond colour scale.

COLOURLESS DIAMONDS

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

FIND YOUR SHADE

Finding a D diamond colour 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 colour 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 colour 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.

Peso en quilates del diamante

Title:

Escala de quilates de los diamantes creados en laboratorio

Subtitle:
La medición en quilates proviene de la palabra «carob», una semilla que los comerciantes de la antigüedad utilizaban como referencia para pesar los diamantes. El quilate es una unidad de medida estándar internacional para pesar el diamante. Un quilate equivale a 200 miligramos, de manera que 5 quilates equivalen a 1 gramo. Los quilates del diamante no hacen referencia al tamaño de la piedra, sino únicamente a su peso. Los diamantes con más quilates suelen ser más caros.

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, 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?

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.
