Diamond color grade

D-grade: The color of D-grade diamonds is completely colorless, which is the highest among the diamond grades. But diamonds of this grade are very scarce, so the price is also very high.

Class e: colorless. Consumers can't tell the difference with the naked eye. Only professional gemologists can distinguish the trace elements contained in diamonds with the help of special machines, so they are very rare.

Class F: All belong to colorless class. Jewelry appraisers can hardly see the yellow element, so it is also a high-quality diamond.

G-H grade: close to colorless grade. Only by comparing with high-quality diamonds can we see the difference, so the quality of diamonds is still very high.

Grade I-J: a small amount of yellow elements can be seen by naked eyes.

K-N grade: The yellow element of diamond can be observed by naked eyes.
