What are the 4Cs of Diamonds?

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

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

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

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.

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 lab 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

Lab 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

Che cosa sono le 4C?

Ogni diamante differisce lievemente dall’altro e presenta caratteristiche distintive. I nostri diamanti creati in laboratorio sono diamanti al 100% e, proprio come i diamanti estratti in miniera, vengono classificati secondo le 4C per la valutazione di qualità del diamante. Le 4C sono le abbreviazioni di color (colore), clarity (purezza), cut (taglio) e carat weight (peso in carati) e rappresentano gli standard universalmente riconosciuti per valutare la qualità di un diamante.

La purezza del diamante è importante?

A un maggiore grado di purezza corrispondono minori inclusioni o imperfezioni del diamante. Questo conferisce al diamante una qualità superiore rispetto ad un altro diamante di grado inferiore.

Qual è la massima 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 di caratteristiche esterne (imperfezioni) e interne (inclusioni), nonché la loro dimensione e posizione, determinano il grado di purezza.

I gemmologi classificano i diamanti dal grado di qualità più alta, Internally Flawless (IF, privo di inclusioni), al grado Included (I3, incluso).

I diamanti creati in laboratorio sono di qualità ineccepibile?

No, quasi tutti i diamanti (estratti o creati in laboratorio) presentano inclusioni. Nei diamanti di laboratorio possono verificarsi inclusioni metalliche. Se un esperto individua una traccia di metallo in un diamante, può presumere che sia stato creato in laboratorio. Sebbene esistano diamanti artificiali che presentano difetti, Swarovski utilizza esclusivamente quelli di alta qualità e certificati dall’Istituto Gemmologico Internazionale (IGI) secondo le 4C, in modo da garantire che solo diamanti della migliore qualità siano inclusi nelle collezioni Swarovski Created Diamonds.

I diamanti creati in laboratorio diventano opachi?

No, i diamanti creati in laboratorio non si opacizzano col tempo. Sono identici al 100% ai diamanti con le stesse proprietà fisiche e chimiche e non si degradano e non cambiano aspetto nel tempo. Se sono stati utilizzati semi di diamante di scarsa qualità, alcuni diamanti di laboratorio presentano difetti evidenti, come sfumature di colore dovute a impurità nel diamante o imperfezioni strutturali del cristallo. I diamanti creati in laboratorio elaborati nei gioielli Swarovski Created Diamonds soddisfano u o standard di qualità molto elevato e non presentano caratteristiche innaturali e problematiche.

Come vengono certificati e classificati i diamanti creati in laboratorio?

I diamanti creati in laboratorio elaborati nei gioielli Swarovski Created Diamonds vengono selezionati manualmente ed esaminati da gemmologi esperti per garantire che soddisfino i nostri elevati standard di qualità. Ogni gioiello delle collezioni Galaxy ed Eternity è accompagnato da un rapporto di laboratorio digitale redatto dall’Istituto Gemmologico Internazionale (IGI).

Che cosa sono le sfaccettature del diamante?

Le sfaccettature del diamante si riferiscono ad ognisuperficie piana che crea la forma di un diamante. Ogni diamante presenta molteplici sfaccettature che gli consentono di assorbire e riflettere la luce.

Come si determina la qualità del taglio del diamante?

Spesso si pensa al taglio di un diamante come alla sua forma (rotonda, a cuore, ovale, marchesa, pera), ma il taglio del diamante si riferisce in realtà alla qualità dell’interazione delle sue sfaccettature con la luce. Il taglio di un diamante è la sintesi della qualità della forma, della geometria e della finitura del diamante. I diamanti rotondi e brillanti vengono classificati formalmente su una scala che varia da Ideal (il migliore) a Poor (di scarsa qualità). Swarovski non scende a compromessi quando si tratta della qualità del taglio e garantisce che tutti i nostri diamanti creati in laboratorio offrano una resa di luce e una brillantezza ottimali.

Qual è il miglior taglio di 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 diamante una personalità unica, mentre il perfezionamento delle proporzioni, la simmetria e le angolazioni tagliate con precisione degli Swarovski Created Diamonds conferiscono loro una brillante lucentezza. Il taglio migliore presenta un equilibrio tra larghezza e profondità per creare simmetria; inoltre, non è né troppo superficiale né troppo profondo, ma crea il punto perfetto di rifrazione della luce attraverso il diamante, riflettendola all'interno dello stesso e mettendone in evidenza la brillante lucidatura.

Come viene determinato il colore di un diamante?

Colour refers to the natural tint inherent in white diamonds. The industry standard for grading colour is to evaluate each diamond against a master set then assign a letter grade from D (colourless) to Z (light yellow).
The closer the diamond is to being colourless, 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 colour 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.
