Diamonds mainly look at 4C standards, namely cutting, clarity, color, and weight. The evaluation of cutting classification mainly evaluates the ratio and modification of diamond processing. The ratio refers to the ratio of diamond diameter of each part of the diamond. The ratio refers to the advantages and disadvantages of diamond processing technology, such as whether the circularity is standard, whether the size of each aspect is the same, how symmetrical, and the degree of surface polishing. my country's diamond grading standards divide the diamonds into three levels: very, good and general.
The evaluation of the classification classification mainly evaluates the purity of diamonds. The interior of the diamond will have more or less mineral wraps, as well as high -quality drills. Usually use 10 times large mirror to observe the diamond, the appearance is observed, and the diamond clarity level segmentation is subdivided into FL, if, VVS1, VS1, VS2, SI1, SI2, L2, L3 gia divided jewelery into into 23 levels, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, S, T, U, V, X, Y, Z. The best color is D, the better, the better, and it is close to colorless transparency. The lower the more yellow level, the lower. D-F belongs to transparent colorless, G-J belongs to colorless, K-M belongs to slight yellow, n-r belongs to light yellow, S-Z belongs to yellow. N-Z belongs to the scope of color diamonds, and of course there are other colors, such as pink, green, blue
as we all know, the bigger the better, the better, I do n’t need to explain it. This.
Top: Crystal transparency, observing no cotton wool, no ice cracks, no impurities, no scratches, exquisite workmanship, flawless 3A: crystal transparent, observation of the naked eye observation , Exquisite workmanship, close to perfect 2A: Crystals are transparent, containing a small amount of cotton wool, ice cracks, and defects.

Class A: There are minor flaws, such as cloud -like, cotton wool or human impact surface scars, and it is easy to see with the naked eye. 4. AB Class: There are obvious internal contents, large clouds, cotton wool, small ice cracks inside, or obvious human impact scars, but there are no obvious large ice cracks. 5. Grade B: The entire natural crystal has more than half of the fog, cotton wool or obvious large ice cracks, and nails can feel the ice crack. 6.
