THE 4 C'S OF GEMSTONES

Carat

Carat refers to the weight of a gemstone.
In fact, the size of a gemstone is measured
by weight, not by dimension in mm.


One carat is equal to approximately
0.2 grams.


In general, as the carat size of a gemstone increases, price increases at an exponential rate. This happens because larger gemstones are increasingly rarer and therefore more valuable.
