What is Diamond Carat Weight?

Carat weight is the unit of measurement of a diamond’s size based on its weight. The higher the carat weight, the heavier the diamond.

However, it is worthwhile to note that when you compare two diamonds, it is possible that one with a lower carat weight may look visually bigger than another diamond with higher carat weight depending on the diamond’s shape and cut. When the diamond is set on a ring, the settings also play a role in how large the diamond look.

Why Does Carat Weight Matter in Diamonds?

Carat weight is an important factor because it affects both the appearance and the value of the stone. A diamond with a higher carat weight is rarer therefore more valuable. It also look more impressive compared to a diamond with a lower carat weight.


How is Carat Weight Measured in Diamonds?

One carat is equal to 0.2 grams, or 200 milligrams. A diamond’s carat weight is measured using a precise scale that can measure down to one-hundredth of a carat. Carat weight is written as ct in short. 

By understanding the importance of carat weight in diamonds, you can make a more informed decision in your purchase. The eventual price will also depend on the cut, color, and clarity you choose. A professional jeweller will be able to assist you in balancing the 4C’s and narrow down the options that are worth your consideration and ultimately finding a diamond that is best value for your money.
