Diamond Carat (weight)

Carat or Weight

The Weight of a diamond, referred to as carat-weight, is the easiest to understand of the four C’s that make up the quality of a diamond or any other precious stone. It just refers to the actual weight of the diamond expressed in carats, where each metric carat is defined as 200 milligrams, or simply put the weight of a diamond in grams times five. Moreover, each carat can be subdivided into 100 ‘points’ which allows very precise measurements to the hundredth decimal place. Us Gemologists describe the weight of a diamond below one carat by its ‘points’ alone. We will for instance refer to a diamond that weighs 0.25 carats as a ‘twenty-five pointer.’  This precise scale is necessary because prices of diamonds are very much depending on the actual weight of the stone, and a small difference in weight can result in a very large price difference. The most important thing to remember about the diamond weight is that, all else being equal, the higher the weight, the higher the price.
