All about Carat

UPDATED:

What does “Carat” stand for? How big is a one carat diamond? How much does it cost?

1. What does Carat stand for?

  • Carat is not the size

Although many people tend to believe that carat relates to the size of a diamond, the carat measurement actually refers to the weight of a diamond.

  • Carat is the weight of a diamond

A one carat diamond weighs 0,2 grams.

2. Carat weight vs size?

The bigger the carat, the heavier the stone, which of course also means that the stone will be larger.

The tables and pictures below will show you how - for each diamond shape - the measurements of a diamond vary with its carat weight.

Note: The tables below serve as indication only. The exact measurements of a diamond can be found in its GIA certificate, which you should always open and carefully read before buying one. Learn how to read a GIA certificate.
