Diamond Carat Size
Carat weight is the measurement used to describe the size of a diamond or gemstone based on its weight.
Diamond Carat Sizes - Grading Scale
Each diamond or gem is individually weighed to determine that stones carat weight. On the metric scale, 1 carat is equivalent to 200 milligrams, or 0.2 grams.
While carat weight can impact the value of a diamond, it’s important to understand that two diamonds of the same weight may have drastically different values. This is because a diamond’s value takes into account all of the 4Cs, not just carat weight.
