Based on the provided classification, the D grade diamond is considered the best in terms of colorlessness and desirability.
Understanding Diamond Color Grading
Diamond color is graded on a scale that traditionally starts with the letter D and goes down through the alphabet to Z. This grading measures the absence of color in a diamond. The less color a diamond has, the higher its value.
As the reference states, the classification is like the alphabet, except the diamond alphabet starts with the letter D. D is the whitest a diamond can get.
The Top Tier: Colorless Diamonds
The most sought-after and valuable diamonds fall into the "colorless" category. According to the reference:
- D, E, or F, are considered colorless which means that they are the most sought after, and more expensive due to their rarity.
This means that while E and F grades are also excellent and considered colorless, the D grade represents the absolute peak of this scale – the complete absence of color.
| Diamond Grade | Color Description | Desirability/Rarity |
|---|---|---|
| D | Absolutely Colorless (Whitest) | Highest (Most Sought After, Rare) |
| E | Colorless | High (Sought After, Rare) |
| F | Colorless | High (Sought After, Rare) |
Why D is Considered "Best"
- Peak Colorlessness: D grade diamonds have no detectable color, making them the whitest and brightest.
- Rarity: These top grades (D, E, F) are significantly rarer than diamonds with slight or noticeable color tints.
- Value: Their rarity and exceptional lack of color make D grade diamonds the most expensive per carat among their peers in other color grades.
- Most Sought After: As highlighted in the reference, the D, E, and F grades are the most desired by collectors and buyers.
In summary, while the entire D-F range is highly prized for being colorless, the D grade diamond specifically represents the pinnacle of color quality on the scale, making it the "best" in terms of color grading excellence.
