Carat Weight

Carat weight is the weight of the diamond measured in carats. One carat is divided into 100 "points," so that a diamond of 75 points weighs 0.75 carats. Carat weight is the most obvious factor in determining the value of a diamond. But two diamonds of equal carat weights can have very different prices, depending on their quality. Diamonds of high quality can be found in all size ranges.

Here are several ways to express 1 carat:

  • 1 ct.
  • 200 milligrams
  • 1/5 gram
  • 100 points
  • 4 grainer (not often used in retail environment)

It is very important not to mistake carat weight as referring to the dimensions of a diamond. It refers to weight only. Why the distinction? Because weight can hide in different parts of the stone. You can have a) well-cut, b) deep, or c) shallow diamonds. Some may appear larger than others due to its cut.
