Internationally use weight (carat), color, Mingcheng (transparency), and cutting standards to measure the quality of diamonds, referred to as 4C standards. In the weight of the weight, how to divide the diamonds. The weight level of diamonds is divided by unit carats. One carat is calculated with 0.2 grams, which is also equal to 100 points. Under normal circumstances, 1 carat is a dividing line. Diamonds smaller than 1 carat are significantly lower than 1 carat diamond. The most important thing is the classification of color. Diamonds are first divided into colored diamonds and white diamonds. Among them, it is more precious and rare for color diamonds such as red, pink, blue, and green. The most common is white diamonds and yellow diamonds. The more pure the color diamonds, the higher the color, the higher the transparency, and the higher the price. Under the magnifying glass, the color of the diamond is many. Taking white diamonds as an example, the 100 -point color diamond rating is D -color, 99 points into E color, and so on, until the white diamonds that are rated into J -colors are still called the naked eye white diamond, and the white diamonds of the K and the following level are called It is a non -white diamond (because the color can be yellowed by the naked eye) The diamond clarity is also a standard for the classification of the diamond. The clarity of diamond simply speaking, how much the impurities inside the diamond are. If the less impurities inside the diamond, the more unknown the location, the higher the diamond level, and otherwise it is low. The ratings of the clarity are from good to secondary order: FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, SI3, P/i2, P/i3. The diamond cutting. The reason why diamond shows the glorious side is mainly after cutting. This is also the problem of diamond cutting. How to classify the diamond is also very important to cut this piece. High -level cutting levels, diamonds are beautiful and high. The cut rating is from good to secondary: EX, VG, G, P.

The quality assessment of diamonds is a global 4C standard.
