The 4C standard for diamonds refers to: Carat, Cut, Diamond, and Clarity should be considered in the following four aspects (4C): (1) Color: It is better to use no color, and the deeper the color, the worse the quality. In the color grading of colorless diamonds, the top color is D color, which is arranged down to Z in turn. We only say the color level from D to J here, DG is colorless, GJ is near colorless, from K There is basically no collection and wearing meaning down. Because the diamond from K down will gradually become yellowish. When we choose the diamond, we should choose the color above H. The level of IJ is also near the colorless category, but it can be perceived as a slight yellow. Colored diamonds, such as red, pink, green, blue, etc., are also treasures in diamonds and are expensive. Among them, red diamonds are more expensive. (2) Clarity: The basis for the classification of clarity is based on the location, size and quantity of inclusions. The level of clarity from high to low can be divided into FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, SI3, P1, P2, and P3. The degree of cleanliness of the diamond should be carefully observed under a ten-fold microscope. The more the sputum, the more obvious the position, the worse the quality and the correspondingly lower price. (3) Carat weight (Carat): In the case of the other three C, the price of the diamond is proportional to the square of the weight. The greater the weight, the higher the value. The weight of a diamond is in carats. 1 carat (ct) = 0.2 g (g). Divide one carat into one hundred, each one is one point, the price tag of the mall is 0.3ct, and 0.4ct is 30 minutes and 40 minutes. (4) Cut: The original stone of a diamond, even if it is thrown onto the road, no one will pay attention. It is the second life of the cut, which gives it a beautiful fire. Cutting refers to the geometry of the various lobe surfaces of the finished loose diamond and its arrangement. The cutting is divided into cutting ratio, polishing and modification. Each item has five levels, from high to low, EXCELLENT, VERYG OOD, GOOD, FAIR, POOR. Generally we see standard round diamond cutting. A perfectly cut stone that achieves a near perfect ratio for light reflection.
