men’s jewelry bracelets Talking about the “carat” of gem weight

Diposting di oleh Kingjy

nyatanya, the seeds of carob are not the same weight. In recent years, some people in our country have collected hundreds of these seeds. After weighing them with a precision balance, they know that their actual mass is 143-240mg, which shows the big difference. Today, when the measurement method is becoming more sophisticated, countries have set a standard quality for carats. At the beginning, it was not uniform. In some countries, 210 mg was 1 ct, while in other countries, 180 mg was 1 ct. In 1877, Britain, Perancis, and the Netherlands, the major gem trading countries at the time, agreed that 205mg was 1ct. In 1907, in order to facilitate conversion to the metric system, the world unified regulations:

1ct = 200mg = 0.2g

This is called “Metric Carat”.

Since diamonds are very precious, diamonds as small as 0.01ct are also useful. In order to easily explain the quality of small diamonds, foreign countries use “Point”, the quality of which is:

1ct = 100Point

Point is translated as “分” according to Chinese custom, yaitu, 1ct = 100 points. It is very convenient to use points to express the quality of small diamonds. Misalnya, a small diamond weighing 0.01ct can be called a 1-point diamond, a small diamond weighing 0.04ct is called a 4-point diamond, and a 20-point diamond is a diamond weighing 0.2g.
