Ct is basically used in medical examinations in our brains. In fact, Ct is the representative of many different units. For friends in the jewelry industry, Ct is the weight unit of gemstones, which is carat. I believe Xiaobian said that this friend is also very familiar with this, then continue to learn more about Ct with Xiaobian! What unit is Ct: the weight unit of Ct gemstone Carat (symbol: CT) 1 carat = 0.2 g (200 mg) As a unit of measurement for gemstones, carat is the legal unit of measurement in the current international standards. Its conversion formula is: 1 carat = 200 mg = 0.2 g. From ancient times to today, in the world of gemstone trade for hundreds of years, jewelers in various countries have become accustomed to using carat as the standard of weighing. The word Carat originated in ancient Greek and was translated from the name of a tree on the eastern shore of the Mediterranean. Before people have a precision balance, they have been using this very uniform and not easy-to-obtain tree seed as the weight of a gemstone. One seed is 1 carat, and the weight of one gem is equal to the number of seeds. . With the invention and use of precision balances in the world, countries have defined carats as standard weight. The weight of the original carat is different in different countries. Some countries set 210 mg to 1 carat, and some 180 mg to 1 carat, while Britain, France and other countries require 1 carat to be 205 mg. Later, in order to facilitate the conversion of the formula, 1 carat was changed to 200 mg in 1907, so it was called metric carat. The value of carat is an important factor in determining the value of a gem. Therefore, if the jewel's carat value is higher, its value will be greater. A diamond was discovered in South Africa in 1905, the largest diamond ever discovered in human history in the world. The largest diamond currently preserved in China was discovered in Shandong in 1977, named Changlin Diamond, and is housed in the People's Bank of China. The weight of a diamond is calculated in carats (also known as cards). 1 carat = 200 mg = 0.2 g. One carat is divided into one hundred, each one is called one. 0.75 carats are also called 75 points, 0.02 carats are 2 points, and 0.1 carats are 10 points. In the case of other similar conditions, as the diamond increases, its value increases geometrically; the same weight of diamonds will vary greatly in color, clarity, and cut.
