Carat
The carat weight is the last decision to make when it comes time to choosing the right diamond. People tend to make the mistake of buying the biggest diamond they can afford without taking into consideration color, clarity, or quality. It is important to keep in mind that if the diamond you choose is less than ¾ carat it is preferable to choose color over clarity. Vice versa when buying a larger stone; clarity overrides the importance of color. It is important to note as well, that a two carat stone is not necessarily twice as big as a one carat stone; it is only greater in weight.
