Diamond Carat

The 4 C’s: Carat

The term "Carat" comes from the carob seed, once used as the standard unit for diamond weight measurement due to its small, consistent size.

Carat weight is the only objective measure among the 4Cs that reflects a diamond’s physical weight. One carat equals 0.2 grams (200 mg). Carat directly impacts a diamond’s size, visual appearance, and price.

During cutting and polishing, diamonds can lose up to two-thirds of their original weight. Generally, larger carat diamonds cost more, but remember that diamond cut and clarity also affect overall value.

Carat and Diamond Diameter Size

Many people often confuse carat with size, but in reality, carat is a unit of weight, not a direct measurement of a diamond’s dimensions. The apparent size of a diamond depends on several factors, including its shape, weight distribution, and cut quality. This means that two diamonds with the same carat weight may look noticeably different in size.

Choose the diamond carat size that suits you

Budget determines carat range.
Carat weight is one of the biggest factors influencing price. Having a clear budget will help you choose the right diamond size.
Consider finger size and wearing habits.
A large carat diamond may look out of place on those with thin fingers; a smaller diamond will create a more elegant and natural look.
Pairing with the setting design.
A cleverly designed setting, such as one with thin prongs or a halo setting, can make a diamond appear larger.
Daily wear needs.
Work environment or lifestyle will determine the diamond size you choose: For active or everyday wear requiring durability, a smaller carat or a secure setting is recommended.
Weighing apparent size against actual carat.
Different cuts significantly affect the perceived size of a diamond. With a high-quality cut, a smaller carat can still achieve the desired visual effect.
