Diamond Carat

Carat is the unit of measurement used to describe a diamond’s weight. One carat equals 200 milligrams (0.2 grams) and is divided into 100 points — for example, a 0.50 carat diamond is 50 points, while a 1.00 carat diamond is 100 points.

It’s important not to confuse carat weight with size. The cut and shape of a diamond can influence how large it appears. A well-proportioned stone can look larger than a deeper or poorly cut one of the same weight.

The Carat Weight Scale

Diamonds can range from a fraction of a carat to hundreds of carats, with each range offering different characteristics and uses:

Under 0.50 carats
Often used as accent or side stones in fine jewelry.

0.50 to 3 carats
The most popular range for engagement rings and other statement pieces. A 1.00 carat diamond is considered a classic benchmark for center stones.

5 carats and above
Rare and highly sought-after, these are often reserved for exceptional high jewelry creations.

Carat Weight and Rarity

While larger diamonds are rarer and often more valuable, two diamonds of identical carat weight can differ greatly in price depending on their cut, color, and clarity. This is why carat should be considered alongside the other 4Cs when selecting a stone.
