クラリティの原則と要素
ラボラトリー・グロウン・ダイヤモンドのクラリティは、そのフロー（欠陥）の度合いによって決まります。すべてのストーンには、ユニークな個性と魅力をもたらすインクルージョンやブレミッシュがあり、その多くは顕微鏡でしか見えません。ダイヤモンドのクラリティの尺度は、フローレス（FL）からインクルーデッド（I3）まであります。この尺度が低いと、インクルージョンがダイヤモンドの透明度、輝き、耐久性に影響を与える可能性があります。

Title:ダイヤモンドのクラリティの尺度と等級
Subtitle:
ダイヤモンドのクラリティの尺度は、インクルージョンとブレミッシュという自然に発じる2つの特性に基づきストーンの純度を示すために使用されます。表面の傷（ブレミッシュ）および内部の不純物（インクルージョン）の数、性質、大きさ、位置により、ダイヤモンドのクラリティの等級が決まります。ダイヤモンドのクラリティの等級は、標準的な検査条件である10倍拡大で判定されます。IFはインクルージョンのない完璧なダイヤモンド、I3は明らかに目視できるインクルージョンのあるダイヤモンドです。
ダイヤモンドのカットとは？
カットの質はクラフツマンシップにかかっています。クラフツマンシップとは、すなわち、1粒1粒のダイヤモンドのファセットと光の相乗効果を生み出し、内なる煌めきを引き出すテクニックです。カットがそれぞれのストーンに個性を与え、完璧なプロポーション、対称性、角度の精度の条件がそろった時、ラボラトリー・グロウン・ダイヤモンドは最大限の輝きを放ちます。
カットの原則と要素
ラボラトリー・グロウン・ダイヤモンドのカットの質は、そのプロポーション、対称性、研磨の3つの要素に基づいて評価されます。エキスパートによるカットで、光を吸収し反射するいくつもの完璧に作られたファセットが生まれ、どの角度から見てもストーンが輝きを放ちます。カットを評価する際、鑑定者はダイヤモンドの表面の外観、デザイン、およびクラフツマンシップを考慮します。
Formes des diamants de synthèse
Les collections de Swarovski Created Diamonds présentent une gamme de différentes formes et tailles de diamants de synthèse. La forme d’un diamant de synthèse se réfère à son contour ou à sa forme externe, vue de dessus. La taille est un indicateur de qualité, reflétant la qualité du travail de facettage et de polissage, ainsi que la manière dont les angles et proportions de chaque facette ont été conçus pour interagir avec la lumière. Choisissez l’une de nos formes de Swarovski Created Diamonds pour refléter votre style individuel. Chaque pierre est taillée pour offrir la brillance, elle ajoutera de la luminosité à toutes vos tenues.
Couleur : principes et facteurs
La couleur la plus désirable pour un diamant est l’absence totale de couleur. Les pierres incolores sont très prisées mais elles sont également extrêmement rares, tandis que les diamants de moindre qualité peuvent avoir une teinte jaune ou marron. L’échelle de couleur des diamants va de D à Z et les collections Swarovski Created Diamonds n’utilisent que des diamants de synthèse ayant une classification de couleur de D à G.
Incolore
D-F
Presque incolore
G-J
Légèrement teinté
K-M
Très légèrement coloré
N-R
Légèrement coloré
S-Z
Échelle de couleur des diamants
La couleur des diamants est classée sur une échelle allant de D à Z. Les D à F sont utilisés pour désigner des pierres incolores, tandis que celles des catégories S à Z apparaissent dans des nuances de jaune clair ou brun. Les bijoux Swarovski Created Diamonds sont exclusivement composés des diamants de synthèse de qualité supérieure, dont la notation est comprise entre D et G (incolore à presque incolore).
Qu’est-ce que le caratage ?
Un carat désigne l’unité de poids adaptée aux pierres précieuses, dont font partie nos diamants de synthèse. Lorsqu’on compare des diamants, il arrive qu’un diamant ait un poids en carats plus élevé sans nécessairement être plus volumineux. De la même façon, le calibre de deux diamants de caratages identiques pourra varier selon la profondeur de la taille. Un carat pèse un cinquième de gramme et peut être divisé en centièmes.

Tableau du caratage
Title:Échelle des carats des diamants de synthèse
Subtitle:
Le carat est l’unité de mesure standard internationale désignée pour mesurer le poids du diamant. Il fait référence à la graine de caroubier appelée caroube. Les marchands l’utilisaient déjà comme unité de mesure du diamant dans l’antiquité. Un carat équivaut à 200 milligrammes. Un diamant de cinq carats pèsera donc un gramme. Le carat d’un diamant ne correspond pas à la taille d’une pierre, il se réfère simplement à son poids, et les diamants deviennent généralement plus chers à mesure que leur poids en carats augmente.
Qualité assurée
Chaque diamant de synthèse serti dans les bijoux raffinés Swarovski Created Diamonds est évalué et certifié par l’IGI (Institut Gemmologique International), selon les critères des 4Cs universellement reconnus. La taille, la pureté, la couleur et le poids en carats de chaque pierre déterminent sa qualité et sa valeur. Swarovski utilise uniquement des diamants de synthèse de haute qualité classés G+ en couleur et VS+ en pureté.

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).

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.
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.
