Changes in each grade have a greater impact on the price of diamonds. So what is the grading standard for diamond clarity? On what basis is diamond clarity graded? Let's take a look together below.　　　　 What is the diamond clarity grading standard? Natural diamonds are formed by carbon in an environment of high temperature and high pressure, and this naturally formed style will have some flaws. Different types of flaws have different effects on clarity. It includes two types: internal flaws and external flaws. . Internal blemishes refer to blemishes in the diamond that can reach the surface of the diamond. It is very important to observe internal flaws because they are the main factor in determining the clarity level of a diamond.　　　　 Internal flaws in the diamond are called “inclusions”, and external flaws in the diamond are called “surface features”. Diamond inclusion type: 　　　　 The evaluation of diamond clarity grade, including the identification of the number, size, visibility, type, location and degree of influence on the overall appearance of the diamond: 　　　　Quantity: When all other factors are the same, in Observed under a 10x magnifying glass, the more visible inclusions or reflection images of inclusions facing up, the greater the impact on the clarity level.　　　　Size: When all other factors are the same, the larger and more obvious the inclusions, the lower the diamond's clarity grade.　　　　Visibility: Refers to the contrast between the inclusions and the diamond. Generally speaking, the greater the difference in brightness or color between the inclusions and the diamond, the more obvious it will have a greater impact on clarity.　　　　 Inclusion or surface feature type: refers to the type of feature and its inherent impact on the diamond. In other words, some inclusions or surface features have a greater impact on clarity.　　　　 Location: Refers to the location of the contents. The closer the inclusions are to the center of the table, the greater their impact on the clarity level.　　　　 In fact, the inclusions and surface features of diamonds are usually very small, and only a professional diamond appraiser can see it. In the eyes of ordinary people, VS1 grade diamonds and SI2 grade diamonds may be exactly the same, but their overall quality is very different, and the price will be much different. Therefore, professional and accurate diamond clarity appraisal is very important.　　　　 How do you see the clarity of a diamond? Ordinary consumers can only observe with the naked eye because they don’t have special tools when observing. First of all, they have to look at the table to see if there is something inside the diamond, such as black minerals, transparent abnormal objects, etc. Observe the internal characteristics of the diamond from the side. If conditions permit, you can also use a magnifying glass to watch.　　　　 Is diamond clarity important? Clarity is an important factor that affects the sparkle of a diamond (second only to the cut). If the clarity of the diamond is poor, the path of light refraction and reflection inside the diamond is blocked by inclusions, and the diamond loses its sparkle. The whole diamond looks no different from glass, and it loses what we usually call the 'flash'. Therefore, the choice of diamond clarity is still more important for diamonds.　　　　How to choose the diamond clarity grade? For ordinary diamonds that are generally worn, it is recommended to choose a flawless grade, that is, no flaws can be seen with the naked eye, then the SI1 and SI2 clarity grades that meet this condition and are slightly cheaper are the clarity grades. Inclusions that are easier (SI1) or very easy (SI2) to see, but no obvious flaws are visible to the naked eye.　　　　 investment collection diamonds are recommended to have a slightly higher clarity grade, such as FL (highest clarity level). When viewed under a 10x magnifying glass, no inclusions or surface features can be seen. Of course, the value of diamonds that meet this level is relatively high, which is several times more expensive than SI1 and SI2.　　　　 What is the diamond clarity grading standard? Through the above introduction, I believe everyone understands that knowledge of diamond clarity determines one of the factors that determine the value of diamonds, and consumers must consider the weight, color, cut and other aspects of the diamond when buying diamonds.
