Calculating formula

1. (Diamond and other weight units) carat (= 200 mg)
2. The purity is 18/24 = 75%
3. The price of diamonds = the basic price of the square* 1 carat market with weight. 1 gram = 100 points, 1 gram = 5 carats of diamonds that have been cut out of the size of one carat, you need to dig 250 tons of mineral soil to obtain. It can be seen that the diamond is expensive.
The standards for measuring the quality and value of diamonds, that is, color, clarity, cara number, and car worker (CUT)-this standard is called 4C. Carat: The weight of the diamond is based on carats, and each carat is 100 points. One carat is equal to 0.2 grams, so a 0.50 carat diamond is equivalent to 50 points. It is a heavy unit evolved from rice beans. The seeds contained in the pods of rice beans or locust trees are very close to each weight, so they are used as tools for weighing diamonds in the early days. Cera is the easiest to be determined in 4C, but the two diamonds with the same weight will be very different in terms of value because of the different car workers, color and clarity. Usually the larger the diamond, the more rare.
The diamond is mostly used to inlaid on the diamond ring. Diamond ring is a diamond jewelry worn on the fingers. Diamonds are the hardest of gems.

1. (weight unit of diamonds, etc.) carat (= 200 mg)
2. (the purity unit of gold) is opened, and the percentage purity is 24. If 18 is opened, the purity is 18/24 = 75 % [Edit this paragraph] Sycla (CT), English carat, is usually abbreviated as CT, [1] Since 1907, it is used as a gem metering unit in 1907. Proportion. Evaluate the international standard of diamond 4C. 4C refers to color, clarity, weight, and cut (cut).
The word carat, derived from the carat "keration" in Greek, refers to long -horn bean trees (or rice bean carobseed), which is a plant widely popular from East Asia to the Middle East. Because its fruits are called nearly consistent weight, and the weight of diamonds is the easiest characteristic of 4C, the early long -horn bean trees are used as a heavy unit for jewelry and precious metals. One carat is equal to the weight of a small horn tree.
In 1983, Mr. Tao Zhengzhang, the Chengdu Institute of Geology (now Chengdu University of Technology), conducted a specific study to confirm that Clarge as the seeds of horn trees in the Mediterranean region-rice beans. About 200 mg, it has nothing to do with the weight of some people said that the weight of Abixinia, Bruce Spikes and locust tree beans. It was not standardized until the beginning of the 20th century.
The public carat unit, that is, one carat is equal to 200 mg. Before 1907, one carat was equal to 205 mg, which is 0.205 grams.
1 carat (CT) = 200 mg (mg) = 0.2 grams (g)
1 carat can be divided into 100 copies to calculate a small gem. Because the density of diamonds is basically the same, the heavier the diamond is the larger. The bigger the diamond, the higher the value of each carat.
The public carat unit, that is, one carat is equivalent to 200 mg, and has been adopted since 1907. Before that, one carat was equal to 205 mg, which is 0.205 grams. [Edit this paragraph] Measurement carat (CT) is the quality (weight) unit of gems, and 1 carat is currently equal to 0.2 grams or 200 mg. One carat is divided into 100 points, such as 50 points, which is 0.5 carats, to calculate a small gem. Because the density of diamonds is basically the same, the heavier the diamond is the larger. The bigger the diamond, the higher the value of each carat.
The 1 carat = 200 mg = 0.2 grams. In the old gem book, one carat is about 205.3 mg. If it is converted to the current carat, one carat must multiply 1.0265. Here is just a rough saying that the carat value in the old countries or regions is different.
Diamonds with a weight of less than 1 carat usually use "points" as a measurement unit, 1 carat = 100 points. In the diamond certificate, the weight of the diamond is accurate to the third place after the decimal point.
The electronic balance with an accuracy of 0.00001 carats is called accurate diamond weight. The diamond weight is recorded in the diamond appraisal report and accurately reaches two digits after the decimal point. So a 25 -point diamond weighs 0.25 carats. Diamonds of the same quality, the larger the weight, the more precious. [Edit this paragraph] The purity of the purity precious metal (gold, silver, platinum, etc.) can be used as the weight ratio of the "expensive" composition and the total amount, with a total amount of 24. Taking gold as an example, pure gold is 24K; 18K is the weight of 18/24, and it is metal for alloy in 6/24.
x = 24 mg/mtotal, and it can be understood as: x/24 = mg/mtotal
x is the number of cards, mg is precious metal weight, and mtotal is the total weight.
