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 color, 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 color 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

Diamond Clarity Chart
Title: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 laboratory grown diamonds gives them their brilliant shine.
Cut Principles and Factors
Title:
The quality of how a laboratory 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.

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
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.

Diamond Carat Weight
Title:Laboratory 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.

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?
As facetas de um diamante são cada superfície plana que cria a forma de um diamante. Todos os diamantes possuem múltiplas facetas que permitem absorver e refletir a luz.
Como é determinada a qualidade do corte do diamante?
Frequentemente pensamos no corte de um diamante enquanto forma (redondo, coração, oval, marquise, pera), mas o que o corte do diamante realmente significa é como as facetas de um diamante interagem com a luz. O corte de um diamante é a medida da qualidade da forma, geometria e acabamento do diamante. Os diamantes redondos brilhantes recebem uma classificação formal de corte numa escala de Ideal (o melhor) a Pobre. A Swarovski é inflexível quanto à qualidade do corte para garantir que todos os nossos diamantes criados em laboratório tenham desempenho de luz e brilho ideais.
Qual é o melhor corte de diamante?
Corte refere-se a como as facetas de um diamante interagem com a luz para revelar seu fogo interno. É o corte que confere a cada diamante a sua personalidade, e aperfeiçoar as proporções, simetria e ângulos de corte precisos dos diamantes criados em laboratório Swarovski Created Diamonds confere-lhes o seu brilho deslumbrante. O melhor corte tem um equilíbrio entre a largura e a profundidade para criar simetria, nem muito raso nem muito profundo. Criando o ponto de refração perfeito para a luz através do diamante, refletindo-a dentro do diamante e destacando o seu brilho polido.
Como é determinada a cor de um diamante?
A cor refere-se ao tom natural inerente dos diamantes brancos. O padrão da indústria para classificação de cor é avaliar cada diamante em comparação com um conjunto mestre e, em seguida, atribuir uma classificação de letra de D (incolor) a Z (amarelo claro).
Quanto mais próximo o diamante estiver de ser incolor, maior será a qualidade.
Quanto mais próximo o diamante estiver de ser incolor, maior será a qualidade.
Os diamantes criados em laboratório têm imperfeições?
Quando são utilizadas sementes de diamante de má qualidade, alguns diamantes criados em laboratório apresentam defeitos óbvios, tais como tonalidades de cor devido a impurezas ou imperfeições estruturais. A Swarovski não vende diamantes criados em laboratório com características problemáticas não naturais.
O que é o peso em quilates de um diamante?
Um quilate é uma unidade de peso usada especificamente para medir pedras preciosas, incluindo diamantes criados em laboratório. Um diamante pode ter um peso em quilates mais elevado sem parecer maior, e dois diamantes com o mesmo peso em quilates podem variar em tamanho se um for cortado mais profundamente do que o outro. Um quilate pesa 1/5 de um grama e é dividido em 100 pontos.
Quantos quilates tem um diamante, como é medido e quão importante é?
Os quilates são a unidade padrão de peso dos diamantes e o primeiro passo no processo de classificação. O peso em quilates do diamante é a medida de quanto o diamante pesa. Cada quilate pode ser subdividido em 100 "pontos". Isto permite medições precisas até à centésima casa decimal. O peso de um diamante com menos de um quilate pode ser descrito apenas pelos seus "pontos". Quanto maior for o diamante, mais quilates terá, mas apenas cada pessoa pode decidir quão importante isso é.
É melhor ter um diamante de quilate mais alto?
É uma questão totalmente pessoal. Se procura um diamante maior, deve procurar um quilate mais alto, já que isso indica o peso e, por conseguinte, o tamanho do diamante.
