ABOUT A DIAMOND’S CARAT WEIGHT

A diamond’s weight is measured in what is known as a ‘carat’, which is a small unit of measurement equal to 200 milligrams. Carat is not a measure of a diamond’s size, since cutting a diamond to different proportions can affect its weight. Here is a diagram that shows the relative size of various carat weights in a diamond that is cut to the same proportions:

Note: the diamonds illustrated are not shown actual size.

The most important thing to remember when it comes to a diamond’s carat weight is that it is not the only factor that determines a diamond’s value. In other words, bigger does not necessarily mean better. All four Cs—Cut, Color, Clarity and Carat Weight must be balanced in order to select the ideal diamond.
