Carat I Clarity I Color I Cut
Four major components are used throughout the world to evaluate a diamond's quality and value. They are known as the 4 C's: Cut, Color, Carat and Clarity. Understanding the qualities of the 4C's and how they interact with each other will help you make the right purchase.
Carat,
Carat, abbreviated "ct." is a measure of weight used for diamonds. One carat is equal to 1/5 of a gram (200 milligrams). Stones are measured to the nearest hundredth of a carat. A hundredth of a carat is also called a point. Thus a .10 carat stone can be called either 10 points, or 1/10 of a carat. Small stones like .05, and .10ct are most often referred to by point designations
The carat, as a unit of weight, is derived from the carob seed which was used by early gem traders to weigh diamonds. Since a carat is a unit of measure and not size, two diamonds of the same carat weight may appear to be different sizes depending on how the diamond is cut.
Clarity,
Clarity is an indication of a diamond's purity and is evaluated by viewing the stone under 10x magnification. See below the differences between what you see with the naked eye compared with what you can see with a 10x magnifying loupe. A diamond that is virtually free of interior or exterior inclusions is of the highest quality for nothing interferes with the passage of light through the diamond.
Every diamond is unique and possesses its own individual natural characteristics referred to as inclusions and described as "nature's fingerprints". These inclusions, such as minerals or fractures, appear while diamonds are formed in the earth. They may look like tiny crystals, clouds or feathers. The number, size, color, nature and position of the inclusions determine the clarity of the diamond.
The Clarity Grading Scale developed by the Gemological Institute of America (GIA), outlined below is the most widely
