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。
Laboratory Grown Diamond Shapes
Swarovski Created Diamonds collections feature a range of different laboratory grown diamond shapes and cuts. The shape of a laboratory grown diamond refers to its outline or external form when viewed from above. Cut is a marker of quality, reflecting how well the stone has been faceted and polished as well as how the angles and proportions of each facet have been crafted to interact with the light. Choose one of our Swarovski Created Diamonds shapes to reflect your individual style and, as each stone is cut for brilliance, it will add luminosity to any look.
Color Principles and Factors
The most desirable diamond color is no color at all. Colorless stones are highly prized but they are also extremely rare, whereas lower quality diamonds can have a yellow or brown tone. The diamond color scale ranges from D to Z and Swarovski Created Diamonds collections only use laboratory grown diamonds with a color rating of D-G.

D-F
Near colorless
G-J
Slightly tinted
K-M

Diamond color scale
Diamond color is rated on a scale from D to Z. D to F are used to denote colorless stones, while those in the S to Z categories appear in shades of light yellow or brown. Swarovski Created Diamonds jewelry only uses the finest laboratory grown diamonds, meaning they range from colorless to near colorless (D-G).
What is Diamond Carat Weight?
A carat is a unit of weight used to measure precious stones including laboratory grown diamonds. When comparing diamonds, one can have a higher carat without appearing larger, and two diamonds with the same carat weight can vary in size if one is cut deeper than the other. One carat weighs one-fifth of a gram and can be divided into 100 points.

Diamond Carat Weight Chart
Title:Laboratory grown diamond carat scale
Subtitle:
Carats are the international standard unit of measurement for the weight of a diamond. It derives from the word ‘carob’, a seed that was used as a diamond weight reference for traders in the ancient world. One carat is equal to 200 milligrams so a five carat diamond will weigh one gram. Diamond carat doesn’t equate to the size of a stone, it simply refers to how much it weighs, and diamonds usually become more expensive as their carat weight increases.
Quality Assured
Every laboratory grown diamond set in Swarovski Created Diamonds fine jewelry is assessed and certified by the IGI (International Gemological Institute), using the universally recognized 4Cs. The cut, clarity, color, and carat of each stone determines its quality and worth. Swarovski only uses high quality laboratory grown diamonds rated G+ in color and VS+ in clarity.

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?
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?
La couleur fait référence à la teinte naturelle du diamant blanc. L’usage est de comparer la couleur de chaque diamant avec un échantillon de référence, puis d’attribuer à celui-ci une lettre, allant de D (incolore) à Z (jaune pâle).
Plus le diamant est incolore, meilleure sera jugée la qualité.
Plus le diamant est incolore, meilleure sera jugée la qualité.
Les diamants de laboratoire ont-ils des imperfections ?
Lorsque le grain de carbone utilisé est de qualité inférieure, certains diamants peuvent contenir des défauts apparents, comme des problèmes de tonalités, des impuretés ou des altérations. Swarovski ne commercialise pas de diamants aux défauts artificiels.
Qu’est-ce que le caratage ?
Un carat désigne l’unité de poids spécifiquement adaptée aux pierres précieuses, dont font partie nos diamants créés en laboratoire. Un diamant pourra posséder un caratage 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 1/5ème de gramme et se divise en centièmes.
Qu’est-ce que le caratage du diamant ? A-t-il une importance et comment le mesurer ?
Le carat est l’unité de mesure standard du diamant et le premier critère d’évaluation pour déterminer la valeur de celui-ci. Le caratage mesure le poids du diamant. Chaque carat se divise en centièmes, permettant une mesure des plus précises. Un diamant de moins d’un carat sera exprimé en centièmes. Plus le diamant est gros, plus il contiendra de carats. Mais savoir si cela le rend précieux à vos yeux reste une question très personnelle.
Un caratage élevé est-il préférable ?
C’est une question très personnelle. Si vous souhaitez acquérir un gros diamant, le caratage aura alors son importance car du poids dépend la taille de celui-ci.
