Carat Weight

Carat weight is the unit of measure used when describing a diamonds weight. 1.00-carat equals .20 grams. 1.00-carat also equals 100 points. For example 50 points is .50 carats or half a carat. As the carat weight increases, the value increase exponentially.
For example, ten diamonds weighing .10 points each would equal 1 carat. A 1 carat diamond is worth far more than these ten smaller diamonds, yet their total weight is still 1 carat. The reason for this is that larger diamonds are much more rare, therefore the value increases accordingly.

What does a Carat look like?

Sizes below are based on a well-cut diamond. A poorly cut 1 ct diamond can look like a .85ct diamond from the top. The weight of a poorly cut diamond is in the depth, giving it a smaller appearance from the top than it should be. So why is this done? Simple, the heavier the diamond the more money it is per carat. However, you should expect to receive a large discount for these poorly cut diamonds versus the same size of a very good cut or better.
