A Lack of Color
When a diamond is graded, it is done so based off of the stone's lack of color. The less color a diamond has, the higher its color grade. After cut, color is generally considered the second most important characteristic when selecting a diamond.
Diamonds are graded on a scale of letters ranging from D to Z. The more white, or less color, a diamond has will result in its color grade being closer to D. As a diamond increases in color, the closer the grade will get to Z.
Here's a quick breakdown on Color Grade:
- Absolutely colorless: The highest grade of color. Very rare.
- Colorless: Rare.
- Near colorless.
- Faint Color: Has a slight yellow hue.
- Noticeable color and as the grade gets closer to Z, the more noticeable it gets.
Besides white and yellow diamonds as we've discussed above, diamonds also come in a variety of other colors including blue, pink, purple, orange, green, red, and black.
Can you guess which is the rarest of these?
If you answered blue or red, you're correct!
