tabla y simetría de la talla del diamante

¿Qué es la talla del diamante?

La calidad de la talla depende de la técnica artesanal empleada. El término se refiere a la forma en que las facetas de cada diamante interactúan con la luz y revelan su fuego interno. La talla le da a cada piedra una personalidad diferenciada. Y depurar las proporciones, la simetría y los ángulos precisos de los diamantes creados en laboratorio facilita que el tallado maximice el brillo.
Formas de los diamantes creados en laboratorio
Las colecciones Swarovski Created Diamonds presentan una selección de formas y tallas de diamantes creados en laboratorio. La forma de un diamante creado en laboratorio se refiere a su contorno o forma externa vistos desde la corona. La talla es un indicador de calidad: refleja, por un lado, la perfección de las facetas de la piedra y el pulido de esta; y, por otro, el grado de elaboración de los ángulos y las proporciones de cada una de las facetas de modo que interactúen con la luz. Las formas de Swarovski Created Diamonds que tenemos en nuestro catálogo te permitirán reflejar el estilo que define tu personalidad. Además, al estar compuestas por piedras cuyas tallas maximizan el brillo, le darán ese toque de luminosidad extra a cualquier look.
Principios y factores del color
El color más deseable en un diamante es la ausencia total de color. Las piedras incoloras alcanzan precios muy altos, pero también son extremadamente raras, mientras que los diamantes de menor calidad posiblemente adopten tonos amarillos o marrones. La escala de colores de los diamantes comprende de D a Z, y las colecciones Swarovski Created Diamonds solo utilizan diamantes creados en laboratorio con una clasificación de color D-G.

ダイヤモンドのカラースケール

ダイヤモンドのカラーはDからZのスケールで評価されます。DからFはカラーレス(無色透明)のストーンを示すのに使われ、SからZのカテゴリーのものでは淡いイエローまたはブラウンの色合いが見られます。Swarovski Created Diamondsジュエリーでは、カラーレスからニアカラーレス(D-G)までの範囲の最高品質のラボラトリー・グロウン・ダイヤモンドのみを使用しています。

ダイヤモンドのカラット重量とは?

カラットとは、ラボラトリー・グロウン・ダイヤモンドなどの貴石の測定で使用される重量単位です。ダイヤモンドを比較する際、見た目が大きくなくてもカラットが高い場合があり、カラット数が同じでも、他のものより深くカットされている場合は大きさが異なることがあります。1カラットは1グラムの5分の1の重さで、100分の1を1ポイントと数えます。

ラボラトリー・グロウン・ダイヤモンドのカラット表

Subtitle:
カラットは、ダイヤモンドの重量の国際標準計量単位です。その言葉は、昔の宝石商がダイヤモンドの重さの基準として使った種子である「キャロブ」に由来しています。1カラットは200ミリグラムで、5カラットのダイヤモンドの重量は1グラムになります。ダイヤモンドのカラットはストーンの大きさを示すものではなく、その重さのみを意味します。また、ダイヤモンドは通常、カラット重量が増加するにつれて高価になります。

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?

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.

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.
