    The diamond price and diamond 4C judgment standard:
    wants to know the price of diamonds, you must start with the value of the diamond itself, judge the international standard of diamond value is 4C, the knowledge of diamond 4C is popular:
    1. Carat. International standard unit Cla (CT), 1CT = 0.2G. Domestic "divide", 1 carat = 100 points. The price of diamonds is directly proportional to the weight. As the weight of the diamond increases, its value increases geometrically; at the same time, the same weight of diamonds will generate the price gap due to different color, clarity, and cutting.
    2. Clarity. International standards stipulate that the division of clarity levels is observed from the five aspects of the nature, color, size, quantity, and location of the inner content under ten times the magnifying glass. According to the standards of my country's national inspection, diamond clarity can be subdivided into LC, VVS1, VVS2, VS1, VS2, SI1, SI2, P1, P2, P3, a total of 10 levels. The higher the diamond clarity, the higher the value.
    3. Color (color). Diamond color grading generally refers to the classification of the yellow and brown series. The color of diamonds is divided into 11 levels, in turn: D, E, F, G, H, I, J, K, L, M, N. D is the whitening diamond level. The closer the diamond is, the higher the value, the higher the value. Like the Levis real -name diamond ring like "only one person in life", it does not provide a diamond ring below the K color, and it is not recommended to buy it.
    4. Cut (cut). The cutting of diamonds refers to the accuracy of its grinding ratio and the perfection after the completion. Good cuts should be as good as possible to reflect the brightness and fire of diamonds as possible, and try to maintain the weight of the rough. From high to low to EX (perfect), VG (good), g (good), f (general), Chinese national inspection is divided into: VG (good), g (good).
