Diamond color grading prevalently refers to the colorlessness of diamonds, namely the grade reflects the diamond’s lack of color. Colorlessness allows more light to pass through a diamond, creating a prism effect and giving the diamond its fire.

The standard color grading widely used today, established by the Gemological Institute of America (GIA), ranges from D (colorless) to Z (light yellow). The process of classifying a diamond with regard to its color is conducted by professional diamond graders comparing the assessed diamond to diamonds of known color.

We keep diamonds of various color grades, but most of our diamonds are classified between D and M.
