A diamond's color in reality actually refers to its lack of color, thus grading the whiteness of the gem. A color grade of D is the highest possible, while Z is the lowest. Jos Alukkas only sells diamonds with a color grade of J or higher.
The color manifests itself in a diamond as a pale yellow. This is why a diamond's color grade is based on its lack of color. The less color a diamond has, the higher its color grade. After cut, color is generally considered the second most important factor while selecting a diamond. This is because the human eye tends to first detect a diamond's sparkle and then its color.
At Jos Alukkas, you'll find only the finest diamonds with color graded D-J. Diamonds graded J or better are colorless or near-colorless, with color that is typically undetectable to the unaided eye.
Which Color Should I Choose?
The purist customer should opt for a colorless diamond with a grade of D-F for a diamond with no discernible color.
Absolutely colorless. The highest color grade. Extremely rare
Colorless. Minute traces of color can be detected by an expert gemologist. Considered a rare diamond.
Near-colorless. Color difficult to detect unless compared side-by-side against diamonds of better grades. An excellent value.
Near-colorless. An exceptional value with slightly detectable warmth or tone.
