What does carat weight measure in diamonds?

Carat weight is a direct measurement of how much a diamond weighs. One carat is equivalent to 200 milligrams, and this weight measurement is crucial because it significantly affects a diamond's value. As the carat weight increases, so typically does the price, as larger diamonds are rarer and more desirable.

Understanding carat weight is essential as it helps consumers and jewelers communicate about the diamond’s size and value effectively. It is important to note that the carat weight does not indicate the overall appearance; rather, it is simply a measure of weight, which can influence but does not define the diamond's size depending on its cut and shape.
