Diamond Grading – Carat

Carat Weight: Bigger is not necessarily better

A diamond is measured in carats. One carat is divided into 100 “points,” so that a diamond of 75 points weights .75 carats. Size is the most obvious factor in determining the value of a diamond. But two diamonds of equal size can have very unequal values, depending on their quality. And diamonds of high quality can be found in all size ranges.


When purchasing a diamond at the quarter carat intervals (1/4, 1/2, 3/4, 1.00, etc.) select a one that weighs just below these intervals. For example, if you would like a 3/4 carat diamond, select a .73 carat diamond which will save you hundreds of dollars.

 In addition to educating yourself about the 4c’s, consider the following Diamond Buying Tips.

TIP #1: Obtaining a Gemologist Institute of America (GIA) Diamond Grading Report. The GIA is the international standard you can trust.   Most diamonds are not already graded by the GIA.   However, having a non-certified diamond certified is possible for a cost of $200-$400.  When comparing prices be sure to include in your comparison the GIA Diamond Grading Report cost.

TIP #2: Inspect your stones unmounted. This will allow you to adequately and accurately inspect the diamond.
