Carat is the unit used to measure the weight of a gemstone. When shopping for a gemstone other than diamond, it is critical to also compare the measurements of the stone to judge the size because different gem varieties have different mass, since they are created from different mineral material. 1 carat is equal to 200 milligrams (0.2 grams).

1/4 Carat Diamond 1/3 Carat Diamond 1/2 Carat Diamond 3/4 Carat Diamond 1 Carat Diamond 1 1/2 Carat Diamond 2 Carat Diamond 3 Carat Diamond
1/2 1/3 3/4 1 1 1/2 2 3


This measures the length (long side) of the gemstone. Dimension is important for gemstones because the mass of a gem varies for each mineral family. Therefore, sometimes dimension is a more accurate measurement of size than carat weight.
