The 4Cs Guide of Diamonds

每一顆鑽石都略有不同，都有各自的顯著特徵。培育鑽石除來源外與開採的鑽石在其他方面無異，因此我們的培育鑽石也是根據鑽石分級的 4C 標準進行評估。4C 是指顏色、淨度、切割和克拉重量，是全球公認的評估鑽石品質的標準。

淨度分級越高，鑽石的內含物或瑕疵就越少，其價值也就比分級低的鑽石高。

鑽石淨度是根據內含物和瑕疵這兩種特徵的可見度來衡量鑽石純淨度的等級。 
為評估淨度，鑽石要在 10 倍的放大鏡下進行檢查。外部 (瑕疵) 和內部特徵 (內含物) 的數量和性質，以及它們的大小和位置，決定了鑽石的等級。 
寶石學家對鑽石進行了分級，從最高品質的內無瑕 (IF) 到內含物 (I3) 。

不是，幾乎所有的鑽石 (開採的或實驗室培育的) 都有內含物。培育鑽石可能會含有金屬雜質。如果專家在鑽石中發現金屬痕跡，便可以假定這是培育鑽石。雖然培育的鑽石確實存在瑕疵，但 Swarovski Galaxy 系列只選用經由IGI國際寶石研究院根據 4C 標準認證的優質培育鑽石，以確保 Swarovski Created Diamonds採用的都是品質優良的鑽石。

不會，培育鑽石不會隨著時間的推移而變得混濁。除了來源，它們與開採鑽石在其他方面100% 相同，具有相同的物理和化學特性，不會隨著時間的推移而退化或改變外觀。若使用品質不佳的鑽石種晶，某些實驗室培育的鑽石會有明顯的缺陷，例如：因鑽石中的雜質或晶體結構不完善造成的色差。Swarovski Created Diamonds 首飾所採用的培育鑽石具有極高的品質標準，不會出現反常或有問題的特徵。

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.

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.

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.

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.

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.

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.

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.

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.
