Diamond color * * * is divided into 23 grades, from high-quality colorless in D grade to light yellow or brown in Z grade, and the grades decrease step by step, so does the quality. These 23 grades are divided into several different grades according to the degree of color grade:

Colorless grades: D, E, F, the types of colorless grades are very rare, among which D color is a very good grade color, and it is also the color grade that many diamond rings like to use.

Nearly colorless grades: G, H, I, J, the color is almost invisible to the naked eye, but it will be relatively colored when compared with colorless grades.

Yellowish grade: k, l, m, it is generally difficult to see the color directly. If it is more than 1 carat, the color will be more obvious.

Pale yellow grade: n, o, p, the color visible to the naked eye. Few people will choose such a diamond ring. As for P-grade diamonds, they rarely appear in the public's field of vision, because the jewelry industry has strict control over the color grade of diamonds. Most brand diamond rings use colorless diamonds, such as DR diamond rings that men can only customize once in their lives.
