Quais são os 4Cs dos diamantes?
Title:
Universalmente reconhecidos, os 4Cs são uma luz orientadora no mundo dos diamantes, ajudando a determinar a qualidade e o valor de cada pedra - os 4Cs significam cor, corte, quilate e claridade. Os diamantes criados em laboratório nas coleções Swarovski Created Diamonds são avaliados com base nesses 4Cs pelo IGI, o Instituto Gemológico Internacional. Os diamantes criados em laboratório nestas coleções são de qualidade muito elevada: Cor G+ e clareza VS+.
O que é a clareza de diamante?
A clareza do diamante é uma medida da pureza da pedra, avaliada pela visibilidade de dois tipos de características – inclusões e imperfeições. Para avaliar a clareza, o diamante é inspecionado sob uma ampliação de 10x. O número e a natureza das características externas (imperfeições) e internas (inclusões), bem como o seu tamanho e posição, determinam a classificação de clareza.
Princípios e fatores de clareza
Title:
A clareza de um diamante cultivado em laboratório é julgada pelas suas falhas, ou seja, pelas suas inclusões e imperfeições que lhe conferem um caráter e charme únicos. Descubra mais sobre a clareza dos diamantes abaixo.

Diamond Clarity Chart
Title:Diamond clarity scale and grades
Legenda:
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

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
Legenda:
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?
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?
ダイヤモンドのカットは形状（ラウンド、ハート、楕円形、マーキス、ペア）のことだと思われがちですが、ダイヤモンドカットのグレードは、ダイヤモンドのファセットが光とどのように相互作用するのかを評価します。ダイヤモンドのカットのグレードは、プロポーション、シンメトリー、ポリッシュの3つの要素に基づいて評価されます。ラウンドブリリアントカットのダイヤモンドは、ExcellentからPoorまでのスケールで正式なカットグレードが決められます。 すべてのラボラトリー・グロウン・ダイヤモンドが最高の状態で光を吸収して反射し、その美しさと輝きが最大限に活かされるよう、Swarovskiはカットの品質に妥協を許しません。
最高のダイヤモンドカットとは？
ダイヤモンドカットのグレードは、カットとは、ダイヤモンドのファセットが光とどのように相互作用してファイアーを導き出すかを表すものです。それぞれのストーンに個性を与えるのはカットであり、プロポーション、対称性、および精密なカットの角度を完璧にすることで、ラボラトリー・グロウン・ダイヤモンドに素晴らしい輝きが生まれます。ダイヤモンドの評価は、ダイヤモンドカットのチャートのプロポーション、シンメトリー、ポリッシュという3つの要素によって決まりますが、輝きには最高のストーンカットが一番重要です。 浅すぎず深すぎず、幅と深さのバランスがシンメトリーになるカットが最高とされています。ダイヤモンドの内部を通過する光の完璧な屈折点を作り出し、光をダイヤモンド内で反射させ、磨かれた輝きを際立たせます。
ダイヤモンドのカラーはどのように決まるのでしょうか？
カラーとは、ホワイトダイヤモンドに固有の自然な色合いを指します。カラーグレーディングの業界基準では、マスターストーンに照らしてダイヤモンドを評価し、D（カラーレス）からZ（ライトカラー）までのアルファベットでグレードを評価します。 ダイヤモンドは無色に近いほど品質が高いとされています。
ラボラトリー・グロウン・ダイヤモンドに傷はありますか？
グレードの低いダイヤモンドの種結晶が使用されたラボラトリー・グロウン・ダイヤモンドの中には、不純物による色合いや結晶構造の欠陥といったものが含まれる場合がありますが、優れた品質が認められたラボラトリー・グロウン・ダイヤモンドのみがSwarovski Created Diamondsコレクションに使用されることを許されます。
ダイヤモンドのカラット重量とは？
カラットはラボラトリー・グロウン・ダイヤモンドをはじめとする宝石の重さを測る際に使われる重さの単位です。カラット数が大きくてもそれほど大きく見えない場合や、同じカラット数でもカットの深さによって見た目の大きさが違う場合があります。1カラットは0.2gで、100分の1カラットまで表示されます。
ダイヤモンドのカラット重量とは何ですか？どのように測定され、またどのくらい重要ですか？
カラットはラボラトリー・グロウン・ダイヤモンドをはじめとする宝石の重さを測る際に使われる重さの単位です。ダイヤモンドのカラットはストーンの大きさではなく、単にその重さを指します。1カラットは100分の1まで表示されるため、 小数点以下2桁までの正確な測定が可能になります。1カラット未満のダイヤモンドの重量は、その小数点以下の数字だけで示されている場合もあります。ダイヤモンドは通常、カラット数が大きくなるにつれ高価になりますが、お好みやライフスタイルによってベストなダイヤモンドを選びましょう。
ダイヤモンドはカラットが高いほうが良いのでしょうか？
お客様の好みによって選んでいただくことが重要です。より大きなダイヤモンドをお探しの場合は、カラット数が大きくなるにつれ高価になります。
