The quality of diamonds can be graded on four factors or 4Cs. These are the cut, clarity, color, and carat weight of the diamond. It is very important to know the characteristics of these precious stones while you are purchasing them.
Clarity generally refers to the presence of identifying marks on the surface (blemishes) and inside (inclusion) the diamond. Considering the tremendous amount of pressure used to create diamonds naturally, it is not unnatural to have flaws. The two types of flaws generally include blemishes and inclusions.
The surface flaws are known as blemishes while internal flaws are called inclusions. It is natural for diamonds to have both blemishes and inclusions at the same time. Blemishes may include chips, scratches, and pits. Many times blemishes may occur due to cutting. Inclusions generally include cracks, air bubbles, and non-diamond materials inside the diamond. When it comes to grading diamonds, all flaws are called inclusions.
Diamond color usually refers to the lack of color in a diamond. When it comes to diamond color, the lesser the visible color, the higher is the grade of the diamond.
It can easily be said that the whiter the diamond, the greater its value. The degree of the color of these precious stones is tested over certain levels that generally range from colorless (D) to significantly colored (Z).
Diamonds that have a low rating on the scale have a mucky yellowish or brownish color. Diamonds that are from D to H on the scale are whiter while from grade I some yellow color will be visible.
Generally, the color of the diamond is a result of its composition and so the color does not change over time. A colorless diamond allows more light to pass through than a colored diamond, and thus emit more sparkle and brilliance.
Carat is the unit of measurement used to weigh diamonds.
One carat of diamond generally equals 200 milligrams or 1/5 of a gram (0.2 grams). The term carat comes from the pod of the carob tree, a tree that is located in tropical areas.
The way a diamond is polished and cut affects its brilliance, sparkle and the fire of the stone. When a diamond is cut properly, it allows light to reflect and refract internally and then emit from the top causing a dazzling effect.
If you wish to have unique diamond rings that have amazing sparkle, you have to look for diamonds that are cut with precision. When a diamond is not cut properly, it will emit light through the sides and bottom and not through the top.
This will result in a duller looking diamond, one that has less fire and sparkle. A diamond is known for its brilliance, sparkle, and fire. A proper symmetric cut along with accurate polish can result in more of this dazzling effect.
THE MOST IMPORTANT C IS CUT
Irrespective of its carat weight, color, and clarity, if the fire and brilliance are absent, then the diamond is not that valuable.
A diamonds cut is always difficult to quantify than its color, clarity and carat weight. Cuts vary from a diamond to diamond and how cutters choose to shape, facet and polish the diamond.
