When you are planning on purchasing a diamond it is important that you know as much as possible about how diamonds are classified. There are four topics you need to become familiar with ?

The Four C's of diamonds.

CUT <> COLOR <> CLAIRITY <> CARAT WEIGHT

This is the weight of a diamond measured in carats. As the carat weight of a diamond increases so does its rarity and therefore its price.

One carat is divided into 100 "points," so that a diamond of 75 points weights .75 carats. The carat-weight of a diamond is the easiest measurement to determine. Most importantly, two diamonds can be of equal carat-weight, but their value can differ greatly due to their cut, color, and clarity.
