WHAT IS DIAMOND CARAT WEIGHT?
When most people think of diamond grading, they think of diamond carat. Did you know that carat is not a grade of diamond’s quality, but merely a measure of its weight? Everything else being equal, a diamond’s price should increase with diamond carat weight.
More precisely, a metric “carat” is defined as 200 milligrams. To understand the measurement, you need to know that each carat is divided into 100 equal “points”. Therefore, when a jeweller describes a diamond as a twenty five pointer, they are referring to a 0.25 diamond carat weight.
Along with carats, you will also notice a measurement abbreviated TDW, which stands for total diamond weight. It’s used when the engagement ring is set with multiple diamonds, such as a multi-stone ring, and it marks their total overall diamond weight.
Also remember that the jeweller is not the one grading the diamond. There are standard grading reports done by many agencies around the world. Some are more reliable than others. It’s important to have a jeweller you can trust that will help you decide what diamond is right for you.
