4 Cs Of Diamonds
Various characteristics of diamonds are graded and categorized by the diamond industry. To learn about diamonds is to first learn about the "four Cs" of diamonds -- the four characteristics which are considered the most important in determining a diamond's value:
-
Cut
-
Clarity
-
Color
-
Carat weight
These are the criteria jewelers use when grading diamonds, and they're the ones you'll need to understand to buy the right diamond for you.
And then there's the "Fifth C":
-
Certificates
Cut is probably the most important, and most challenging, of the four Cs to understand. The brilliance of a diamond depends heavily on its cut.
Most diamonds contain some inner flaws, or inclusions, that occur during the formation process. The visibility, number and size of these inclusions determine what is called the clarity of a diamond. Diamonds that are clear create more brilliance, and thus are more highly prized, and priced.
Colorless diamonds are the most desirable since they allow the most refraction of light (sparkle). Off white diamonds absorb light, inhibiting brilliance.
A carat is the unit of weight by which a diamond is measured. Because large diamonds are found less commonly than small diamonds, the price of a diamond rises exponentially to its size. Read this guide to get a better understanding of what a carat is and how it affects the appearance of a diamond.
The diamond certificate, which is sometimes called a grading report, is a complete evaluation of your diamond that has been performed by a qualified professional with the help of special gemological instruments. Each stone bears its own recognizable, individual characteristics, which is listed on the certificate.
