Diamonds' color grades are divided into D, E, F, G-H, I-J, K-M, and N-Z. On the national appraisal certificate, the appraisal conclusion will be issued according to D-E, F-G, H, I-J, K-L, etc. Therefore, diamond g-color is a relatively high level and belongs to diamonds close to colorless grade.
Diamonds are divided into colorless diamonds and colored diamonds. Color diamonds are the highest grade with pure pink diamonds, while colorless diamonds are rare and colorless D-grade from high to low; colorless E-grade, F-grade; near colorless G-H-grade, I-J-grade; K-M-grade and N-Z-grade with darker colors.
At present, the appraisal conclusion of the national appraisal certificate is issued according to D-E, F-G, H, I-J, K-L, etc. Therefore, the g-color of diamonds belongs to the middle and high grade, close to colorless grade. When compared with higher-grade diamonds, such as E-grade and F-grade, the color can be seen, and the cost performance is very high.
Among the colorless to yellow series of diamonds, the closer the diamond is to colorless, the higher the grade, and the higher the value; and the closer the diamond is to yellow, the lower the grade, and the lower the value. Diamonds below Z are called colored diamonds. In colored diamonds, the stronger the hue of the yellow diamond, the higher the value.
