Carat Weight

Contrary to popular belief, carat refers to the weight of the diamond, not necessarily the size. The size is measured in millimeters across the top, as that is how it is viewed when set in a ring. But just as cut grade depends on depth and width, carat weight depends on both factors as well. Two diamonds that appear to be the same size can have different depths and ultimately different carat weights.

Since all diamonds must be cut and polished to remove the outer layer of “rough”, large carat diamonds are understandably rare. Sometimes a diamond is cut to maximize carat weight, resulting in less brilliance or sparkle. Bigger might not be better after all.

Did You Know?Diamond prices noticeably increase at the full- and half-carat weights. If you are looking for a 1-carat diamond for example, you should consider 0.98 or 0.99-carat diamonds because they will appear to be the same size but you can potentially save big.

Use the interactive scale below to help you choose the carat weight that is right for you.

Carat 0.25

1 carat is equivalent to 200 milligrams. Because carat is a record of a diamond’s weight – not its size – two diamonds of slightly different sizes may have the same carat weight. A diamond’s size is also dependent on how evenly its weight is distributed, and the quality of its cut. Some diamonds are cut to maximize carat weight, resulting in less sparkle. A balance of quality in carat and cut is therefore recommended.

For the best value, look at diamonds slightly lighter than the carat weight you initially want. For example, instead of 1-carat diamonds, consider 0.98 and 0.99-carat diamonds. The difference in size will be negligible, but savings here can be significant.ed-carat-0-25

What makes a diamond sparkle? It is created by the cut of the diamond, which is why you should pay close attention to the first of the 4C’s.
