1. According to the weight, diamonds can be divided into seven grades: - 0.30ct~0.39ct: small carat diamonds, suitable for daily wear. - 0.40ct~0.49ct: A slightly larger carat grade, the price is relatively reasonable. - 0.50ct~0.69ct: half-carat to near-carat level, which has a certain value preservation. - 0.70ct~0.89ct: Close to one carat, the price is relatively high.

2. Diamonds are graded using the 4C standard, which is comprehensively evaluated from four dimensions: weight, cutting, color, and clarity. Each dimension contains multiple levels. The following are the specific grading methods and key points: Weight (Carat) unit and conversion: 1 carat =100 points =0.2 grams, the greater the weight, the higher the value. Market rules: Diamonds below 30 points are regarded as broken diamonds and have low value preservation; diamonds below 20 points are usually not classified.

3. Color grade: According to the GIA standard, the color of diamonds is divided into 23 grades from colorless and transparent to yellow. D color is the highest level, indicating complete colorless. As the number of letters increases, the color of the diamond gradually turns yellow, and the Z color is the lowest level. Among them, H color is standard white, and diamonds above H color are getting whiter and whiter, and the difference must be felt under the contrast of different colors; diamonds below K color have obvious yellow color and are not recommended to be purchased as wearing diamonds.

4. The grade of diamonds is mainly divided according to four aspects: weight, clarity, color and cutting. The following is a detailed grade classification: Weight The weight unit of diamonds is carats, and 1 carat is equal to 100 points. The heavier the diamond, the rarer it is, and the higher its value. When other grades are the same, the heavier the diamond, the higher the grade. Clarity Clarity is divided into five levels from F-I.
