The main diamond fraction refers to one of the weight units of diamonds. If it is a modern diamond, 1 carat is equal to 0.2g or 200mg .. One carat is divided into 100 minutes, such as 50 cents or 0.5 carat, which is used to calculate smaller gems. Because the density of gems is basically the same, the heavier the gem, the bigger the volume.

The bigger the gem, the rarer it is, and the higher the value per carat. According to the textual research of Huaxuan Jushi, the unit name of Kela originated from Ghana, a West African country in the13rd century, and its capital Accra is the earliest gold and diamond distribution center in the world. Due to the language communication barriers between countries, trade place names are used as units of measurement.
