What is Diamond Color?
What is Diamond Color?
Color is one of the key considerations when purchasing a diamond. As one of the 4Cs, color plays a significant role in determining a diamond’s quality, rarity, and value. When discussing white diamonds, color actually refers to the absence of color—colorless diamonds are the most highly prized.
Though diamonds are known for their clarity, most naturally contain trace elements that result in subtle hues. The most common tints are yellow, brown, and gray, caused by the presence of elements other than pure carbon. These slight colorations are assessed and graded using the internationally recognized diamond color scale, which assigns a letter grade from D to Z based on hue, tone, and saturation.
The Tinge
Color in diamonds can have a mix of yellow, brown, and grey colors. At Golden Eiffel, we exclusively offer colorless to faint colored diamonds with only yellow tinge because brown and grey hues typically hinder the appearance of colorless to faint colored diamonds, making them look dull.
The International Color Scale
The International Color Scale
In the 1950s, the Gemological Institute of America (GIA) introduced the GIA Color Scale to create a consistent global standard for diamond color grading. Before this, diamond color was described using vague and inconsistent terms like “white,” “blue white,” or “AAAA.”
The GIA Color Scale uses letters from D (completely colorless) to Z (noticeable color). Diamonds are graded in a controlled lab environment, placed face-down on white paper and examined under specialized lighting by a panel of five trained GIA experts. Each expert compares the diamond to a set of master stones and assigns a color grade based on the closest match. If there’s no consensus, the stone undergoes further testing. Thanks to this strict process, the GIA Color Scale has become the universal standard across the diamond industry.
Naming Conventions
The GIA Color Scale is comprised of the alphabetical letters D-Z. The decision to choose D as the foremost letter comes from the intent to avoid confusion with the preceding naming conventions, considering one of the most famous but obscure terms used in the past for color grading include: AAA, AA, A, B, and so on.
Diamond Color Grading
Diamond Color Grading
Golden Eiffel exclusively offers colorless and near-colorless diamonds, with select options of faint-colored diamonds upon request. This ensures we carry only high-quality stones with stunning visual appeal. Colorless diamonds offer exceptional rarity and elegance, while near-colorless and faintly colored diamonds deliver impressive value without compromising beauty.
Colorless Diamonds (D–F)
D, E, and F color diamonds are classified as colorless. When set in white gold, differences between these grades are nearly impossible to distinguish with the naked eye. These diamonds contain no noticeable hues and are the most expensive on the color scale, although pricing can still vary between D, E, and F.
Near Colorless Diamonds (G–J)
G to J color diamonds fall in the near-colorless range. These diamonds may exhibit a faint yellow tint upon close inspection, giving them a warm and elegant character. G and H diamonds are especially popular, offering a similar look to colorless stones at a more accessible price. While I and J diamonds can show subtle color when compared directly to colorless diamonds, most people won’t notice the difference in day-to-day wear.
Faintly Colored Diamonds (K–M)
Diamonds graded K, L, or M display a noticeable yellow tint, appreciated by those who prefer a warmer tone. These diamonds offer excellent value and can look beautiful in yellow or rose gold settings that complement their color.
D Purely colorless and icy white. The very best color grade -- signifies utmost scarcity and value.
E Colorless with minute traces of color observable only by experts. An exquisite, great quality diamond.
F Colorless with slight color detectable by experts. A great quality diamond.
G Near colorless with noticeable tinge when compared to colorless diamonds. Excellent value.
H Near colorless with tangible color when compared to higher grade diamonds. Great value.
I Near colorless with minor noticeable tinge especially when compared to higher colored diamonds. Great value.
J Near colorless with slightly perceptible color. Good value diamond.
K Faintly colored with noticeable color. Good value diamond.
A Good Eye
When looking at diamonds of the same color group, tiny color differences can often be indiscernible even to the most seasoned jewelers. However, since subtle discrepancy between colors suggests the difference in the stones' quality and price, someone with a good eye will know the difference in a glance.

Fancy-Colored Diamonds
Fancy-Colored Diamonds
Some diamonds exhibit vivid hues that fall outside the D–Z range and are classified as fancy-colored diamonds. These rare gems come in a wide spectrum—yellow, pink, blue, green, orange, and more—and are graded based on hue, tone, and saturation, using a different scale than white diamonds.
Fancy-colored diamonds are incredibly rare, and their price reflects this scarcity. Pink, blue, and green diamonds are among the most valuable, while black, brown, and even fancy white diamonds can be more affordable by comparison.
At Golden Eiffel, we offer a curated selection of exceptional fancy-colored diamonds, each chosen for its rarity and distinct style.
How Carat Size Influence Diamond Color
How Carat Size Influence Diamond Color
Carat size can significantly impact how a diamond’s color is perceived. Since color comes from within the stone, a larger diamond will display more visible color than a smaller one of the same grade. For example, an I-color diamond at 3 carats may show more noticeable warmth compared to a 0.50-carat I-color diamond.
For this reason, we recommend selecting a higher color grade when choosing larger diamonds, even if it means a higher price. That said, the most important factor is finding a diamond you genuinely love—one that balances beauty and value according to your preferences.
How Diamond Shape Influence Diamond Color
How Diamond Shape Influence Diamond Color
Diamond shape plays a role in how color is perceived. Round brilliant cuts are best at concealing color thanks to their many facets and light-reflecting angles, making them appear brighter and whiter. In contrast, shapes with larger, open facets—such as emerald, asscher, oval, and pear—tend to show more color.
Interestingly, these same shapes are favored for fancy-colored diamonds, as their structure enhances and showcases the diamond’s natural hue more vividly.
How Jewelry Settings Influence Diamond Color
How Jewelry Settings Influence Diamond Color
The metal used in a jewelry setting can affect how a diamond’s color appears. White gold enhances colorless and near-colorless diamonds, making them look even brighter and cleaner by masking faint tints. On the other hand, yellow or rose gold settings complement diamonds with warmer tones—typically J color and lower—by blending and softening their visible hue, creating a beautiful, cohesive look.
How Diamond Color Influence Price
How Diamond Color Influence Price
Even small differences in color can influence a diamond’s price, particularly when moving between categories or near milestone grades. Because truly colorless diamonds are rarer, they command a premium, while diamonds with slight tints are more common and therefore more affordable.
Interestingly, diamonds at the top or bottom of each category—like F, G, and J colors—often offer the best balance of appearance and price. Even within the same grade, minor variations can shift value by over 10%, making color a key factor in pricing.
How important is diamond color?
Diamond color plays a key role in how a diamond looks, especially in larger stones or certain shapes. While it doesn’t affect sparkle like cut does, a noticeable tint can influence a diamond’s visual appeal and value.
Can I see the difference in color grades with the naked eye?
Most people can't distinguish between adjacent grades (e.g., F vs. G), especially when the diamond is set.
What is the most popular diamond clarity?
Most diamonds contain natural trace elements like nitrogen, which cause slight yellow or brown tints.
What is the most popular diamond color grade?
F is the most sought after diamond color in Golden Eiffel, followed by E, D, and G.
