Diamond Carat Weight

Updated: Mar 9


Diamond Weight and Size

The carat weight of a diamond serves as a measurement of its apparent size.

 

In simpler terms, it quantifies the diamond's mass. One carat is defined as 200 milligrams and is further divided into 100 points, allowing for precise measurements to the hundredth decimal place. Diamonds weighing less than one carat may be referred to solely in points by jewelers; for example, a 0.25-carat diamond may be termed a 'twenty-five pointer.' Conversely, diamonds exceeding one carat are expressed in carats and decimals, such as a 1.08-carat stone being denoted as 'one point oh eight carats.'

 

In general, the price of a diamond tends to rise with an increase in carat weight due to the rarity and heightened desirability of larger diamonds. However, it is crucial to recognize that two diamonds with identical carat weights can exhibit distinct values and prices based on three additional factors encapsulated in the diamond's 4Cs: Color, Clarity, and Cut.

 

Although carat weight is commonly misconstrued as a size indicator, it strictly measures the diamond's weight. It is essential to underscore that a diamond's overall value is determined by considering all elements of the 4Cs, not exclusively relying on carat weight. Furthermore, it is noteworthy to differentiate between carat and size, as they are not synonymous; carat denotes weight, while size pertains to the diamond's dimensions.
