4Cs of Diamonds
You’ve probably heard about the 4Cs of a diamond, and you may even know that it stands for diamond cut, colour, clarity and carat weight. Below we take a closer look into the individual 4Cs.
The colour of gem-quality diamonds occurs in many hues. In the range from colourless to light yellow or light brown. Colourless diamonds are the rarest. Other natural colours (blue, red, pink for example) are known as “fancy,” and their colour grading is different than from white colourless diamonds.
Of all the 4Cs, diamond cut has the greatest effect on a diamond’s beauty. In determining the quality of the cut, the diamond grader evaluates the cutter’s skill in the fashioning of the diamond. The more precise the diamond is cut, the more captivating the diamond is to the eye.
Diamonds can have internal characteristics known as inclusions or external characteristics known as blemishes. Diamonds without inclusions or blemishes are rare; however, most characteristics can only be seen with magnification.
The carat is the diamond’s physical weight measured in metric carats. One carat equals 1/5 gram and is subdivided into 100 points. Carat weight is the most objective grade of the 4Cs.
