Diamond clarity is the quality of diamonds that relates to the existence and visual appearance of internal characteristics of a diamond called inclusions, and surface defects, called blemishes. Clarity is one of the four Cs of diamond grading, the others being carat, color, and cut.

  • Termínem čistota diamantu rozumíme míru nedokonalostí, které kámen obsahuje. Čistota má velmi velký vliv na výslednou cenu prodávaného kamene, protože čím více je diamant dokonalý ve všech aspektech, tím je také dražší. (cs)
  • 鑽石淨度為鑽石視覺上的潔淨程度,為鑽石4C標準之一。影響其等級的瑕疵分為二者,內部的瑕疵稱為內含物(英語:inclusion ),表面的缺陷稱為表面瑕疵(英語:blemish )。評鑑鑽石淨度的準則,包括了上述瑕疵的數量、大小、種類、位置、明顯度等對鑽石整體外觀的影響程度。鑽石淨度的評級必須在十倍放大鏡(Triplet lens)檢視下進行。 內含物可能為包覆在鑽石內的其他礦物晶體,或者本生的晶體缺陷呈現霧狀白色。而大部分的鑽石都含有極細微的內含物,不影響鑽石本身的美感,也無法由肉眼觀察。但較大的內含物會阻礙光線在鑽石內穿透,影響鑽石的閃耀程度。靠近或延伸至表面的裂紋有可能受應力而加長增深,甚至崩裂。 淨度等級越高,鑽石的價格也就隨之增高。此外,內含物記載鑽石形成時的地質環境,並可作為分辨真偽、天然或合成鑽石的依據。 (zh)

  • Diamond clarity is the quality of diamonds that relates to the existence and visual appearance of internal characteristics of a diamond called inclusions, and surface defects, called blemishes. Clarity is one of the four Cs of diamond grading, the others being carat, color, and cut. Inclusions are solids, liquids, or gases that were trapped in a mineral as it formed. They may be crystals of a foreign material or even another diamond crystal, or may have produced structural imperfections, such as tiny cracks that make a diamond appear whitish or cloudy. The number, size, color, relative location, orientation, and visibility of inclusions can all affect the relative clarity of a diamond. A clarity grade is assigned based on the overall appearance of the stone under ten times magnification, which is the standard magnification for loupes used in the gem world. Most inclusions present in gem-quality diamonds do not affect the diamonds' performance or structural integrity and are not visible to the naked eyes. However, large clouds can affect a diamond's ability to transmit and scatter light. Large cracks close to or breaking the surface may reduce a diamond's resistance to fracture. Diamonds with higher clarity grades are more valued, with the exceedingly rare "Flawless" graded diamond fetching the highest price. Minor inclusions or blemishes are useful, as they can be used as unique identifying marks analogous to fingerprints. In addition, as synthetic diamond technology improves and distinguishing between natural and synthetic diamonds becomes more difficult, inclusions or blemishes can be used as proof of natural origin.
