"Carat" is the unit to measure the quality of precious stones and diamonds, and "gram" is the international standard unit of quality. The conversion relationship between them is mass unit conversion, where 1 carat is equal to 0.2g..

The concept of carat originally came from astronomy, indicating the quality of seeds. Later, carat became the quality standard unit in the field of gemstones, defined as 200mg (0.2g).

In the diamond and gem market, quality is an extremely important factor. The carat number of a diamond has an important influence on its value and rarity. Usually, with the increase of the number of carats, the price of precious stones also rises.

It should be noted that carat is only one aspect of evaluating the quality of gemstones. In addition to the number of carats, people also pay attention to factors such as cutting, color and cleanliness. So when buying jewelry, we usually refer to the "four C" standards, that is, carat, cut, color and clarity.

Application of carat

1. Gemstone evaluation: Carat is one of the key indicators of gem quality evaluation. It is directly related to the size of a gem. Usually, the bigger the gem, the higher the number of carats and the greater its value. When consumers buy jewelry, they often choose the right gem according to the number of carats.

2. Diamond market: In the diamond industry, carat is one of the main factors that determine the price of diamonds. The market value of diamonds increases with the increase of carats. Large carats of diamonds are usually rarer, so they are more popular, but also more expensive.

4. Investment: Some investors regard diamonds and other precious stones as an investment method. In this case, the number of carats is regarded as the embodiment of the wealth and value of gems, and investors will make purchase decisions accordingly.
