So, how much do you know about this expensive'stone'? What about the quality of diamonds?　　　　 The quality of diamonds is divided by 4C as the standard, 4C is: weight (carat), color (colour), clarity (clarity), cut (cut). The culture of diamond originated abroad and is a very complicated science. Below we will only briefly introduce these four elements.　　　　 1. Weight (carat)　　　　Weight is the most intuitive and important factor affecting the grade of a diamond. The heavier the weight, the scarcer, and of course the higher the value. The weight of a diamond is measured in carats, 1 carat u003d 0.2 grams. Believe that we have all seen the dove egg in the movie 'Lust CautionThe largest 'pigeon egg' in the world now is Africa Star 2. It is shaped like a water drop, weighs 530.2 carats, and is inlaid on the scepter of the Queen of England.　　　　Second, color (colour)　　　　 The color of diamonds is divided into two series: colorless and colored. The color of colorless diamonds usually ranges from D (transparent and colorless, that is, starting from the first letter of Diamond) to Z (yellow). Fancy colored diamonds are extremely rare diamonds with strong and vivid colors such as pink, blue, green, and very rare red.　　　　 3. Clarity (clarity)　　　　Because diamonds are naturally formed, it is impossible to be completely pure, and there will be certain impurities of different colors inside, which is the flaw of this diamond. We observe the inside and outside of the diamond with a magnifying glass of 10 times. Clarity is a standard for evaluating the impurity content. It is mainly divided into FL, IF, VVS, VS, S and other general grades.　　　　 Fourth, cut (cut) 　　　　 The cut refers to the angle at which the technician cuts the diamond petals and the proportions of each part of the diamond after the cut. A skilled technician will cut out a beautiful and decent diamond sample according to scientific proportions, and cutting too deep or too shallow will greatly affect the value of the diamond. The quality of the cut has the following grades: 　　　　 EX: Ideal cut (EXCELLENT): Only first-class high-quality diamonds can meet the standard. This cut makes the diamond reflect almost all the light entering the diamond.　　　　VG: Very good cut (VERY GOOD): It can make the diamond reflect the light of standard cut, but the price is slightly lower than the previous one.　　　　G: Good cut (GOOD): It can reflect most of the light entering the diamond, but it is much cheaper than the VG grade.　　　　F: General cut (FAIR): Represents rough diamond cut. Although it is a high-quality diamond, the light reflected by the general cut diamond is not as good as the G-level cut.　　　　 P: Poor cut (POOR): This includes all diamonds that do not meet the general cut standards. The cuts of these diamonds are either deep and narrow or shallow and wide, which tends to allow light to escape from the edges or bottom, thereby making the diamond lose its luster.　　　　 The above is the author's summary of diamond grade information for you.
