Diamond Carat Weight Guide

Although commonly thought to refer to the size of a diamond, a carat is actually used to measure a Diamond's carat weight or mass. One carat is defined as exactly 200 milligrams (about 0.007 ounce). The point unit — equal to one one-hundredth of a carat (0.01 carat, or 2 mg) — is commonly used for diamonds of less than one carat. All else being equal, the value of a diamond increases exponentially in relation to carat weight, since larger diamonds are both rarer and more desirable for use as gemstones.

It is important to note that two diamonds with the same carat size might actually apper to be different sizes. Since carat refers to the mass of the diamond, you must also consider the cut. A diamond that is heaver on the bottom, called the pavillion, than the top might appear smaller at the same carat size as a diamond that is cut more narrow on the bottom.

Some consdier the carat the most important attribute of a diamond. You often hear people ask "How many Carats'. This is ok, but be sure to also consider the Diamond Cut, Diamond Clarity, and Diamond Color as well to make sure you are getting right diamond that she will cherish forever.
