Diamond Color Chart, GIA Color Scale and Buying Guide
Posted by Sharif Khan on 21st Jul 2021
Diamond color—one C among the 4Cs used for grading and evaluating diamonds—is a diamond's hue based on the GIA's diamond color scale.
In White diamonds (unlike fancy color diamonds), a diamond with a higher color grade ( Colorless D, E, F) will carry a bigger price tag than a diamond in lower color grades such as J, K, M. Near colorless diamonds are also considered high quality, especially G and H color diamonds.
- D-F Color Diamonds are considered colorless and are suitable for investment purposes. However, a diamond's clarity must also be high for it to be considered in the investment category (Flawless to VVS range). If you are buying a diamond in the D-F color range, diamonds with no fluorescence should be given preference.
- G is also an exceptional color and almost impossible to distinguish from colorless diamonds. For example, between this 1ct. G VS1 and 1ct. F VS1 (other factors being equal), you are saving $1000 without compromising the stone's overall brilliance.
- H and I are also perfect color grades (GIA graded) and can be good options if you want a high-quality diamond but have a budget problem.
- Faint to strong blue fluorescence can be a helpful factor in H-J color diamonds (see below why).
- Color should be prioritized over clarity in high-quality diamonds. If the diamond is eye-clean, its brilliance will not be affected by clarity as much as it would be by color. However, all 4Cs should be prioritized in a balanced manner (see the four scenarios outlined below).
- If you are shopping for a larger stone 2+ct, color is more important because larger stones show more color than smaller ones.
- Metals, such as rose or yellow gold, could be good choices as mountings for I and low color diamonds since they can offset the slightly yellow tint in a white diamond.
Fluorescence in a diamond is a critical subject to understand while considering the color grade of a diamond. In colorless diamonds (D-F), no fluorescence is often better because blue fluorescence can make diamonds look overly bluish. However, in H and above color grades, blue fluorescence can be a helpful factor since it makes the diamond look whiter. It is so because blue is a complementary color to yellow, and the mix of the two turns diamonds whiter.
The color of the metal in which the diamond is mounted can also help make a slightly yellow diamond look whiter. If you go for an H or above color diamond, consider a rose or yellow gold mounting as the metal's reflection will make the diamond look whiter. For D-G color diamonds, white gold or platinum mountings are perfect unless you prefer yellow or rose gold.
Over the past ten+ years, here are the four scenarios that shoppers used as they made their choices about the 4Cs.
Choice 1: Under this category, people went for the highest color and clarity possible. D-F/FL-VVS range with best possible cut and GIA or AGS certification and no fluorescence (we call these investment-grade diamonds, which are highly rare).
Choice 2: Under this option, shoppers aim for a high-quality stone, though the size is also a priority for them. Therefore, they would go for a 1.5 carat stone, G/H color, VS1-2 clarity, very good to excellent cut, GIA/AGS graded with none to medium blue fluorescence. It is our favorite category because these stones are high in circulation and easy to resale as well.
Choice 3: In this range, buyers aim for the largest possible size while hoping to get an eye-clean stone with decent color. Hence, they would go as low as SI1/SI2 clarity range and I-J color with up to strong blue fluorescence.
Choice 4: In this option, the shopper has decided that she/he must give up on one C to maximize on the other 3Cs. In this case, we urge people to compromise on color to get a high clarity and well-cut stone with more considerable carat weight. They would still get optimal fire from the stone, though it would have a warm yellow tint - some people even appreciate the slight yellow shadow in a diamond.
Here is GIA's color scale:

Diamond Color Chart:
You may have heard of the term "fire of a diamond" but have yet to understand what it entails. Diamonds split light just as prisms do. The resultant spectrum displays colorful flashes, referred to as the flame of that diamond. According to the diamond color chart, such a rock has a very substantial grade, and thus you should expect to fork out a fortune for that stone. Furthermore, the color chart gives various descriptions to understand the different grades of color in a diamond.

The AGS's scale is graduated from 0 to 10 (colorless to elaborate yellow), while the GIA's is from D to Z (colorless to light yellow).
As mentioned in the beginning, fluorescence can also influence a diamond's color, i.e., the effects of exposure to ultraviolet rays. Given that it is present in the sun's rays, ultraviolet light affects diamonds both positively and negatively. It gives an unsightly milky white color to colorless stones (thus lowering their value) and a whiter bright shade to lower color diamonds (thus adding value). Ultraviolet light effects may also be unnoticeable in some diamonds.
The setting has a significant influence on the stone's color irrespective of its position in the diamond color chart. As stated, for yellow diamonds, yellow or rose gold settings are advisable, while for colorless diamonds, ta yellow settings should be avoided because it gives the stоnе а yеllоw shаdе. Nonetheless, the setting you choose will affect the stone's final color, and so contemplating on the other Cs will help you end up with the right color. In choosing fancy-colored diamonds, the rarity, richness, and purity of the color are used for the colored diamond's vаluе.
Diamond Color Scale:
When shopping for diamonds, you will most likely come across diamonds that fall into a wide variety of color grades. Even if it is not visible to the naked eye, a slight difference in color grade can have a massive impact on the price of a diamond.

Fancy Color vs White Diamonds:
Fancy-colored diamonds are different from white diamonds. Over 90% of traded diamonds are white, and, therefore, there is a standard industry grading scale for them. On the other hand, colored diamonds do not have a standard grading scale. Fancy color diamonds are highly scarce, valuable, and elegant, especially those with intense color and high clarity.
Shoppers buying colored dіаmоnds will often notice that the рrісе tаg оn thе stоnе wіll bе hіghеr thаn thеіr соlоrlеss соuntеrparts. Since fancy color diamonds can be valuable investment options, they will be an excellent option for anyone who can afford this type of stone.

Which color tier represents the best value?
The diamonds that we most commonly see are clear or colorless diamonds. While white diamonds tend to be somewhat more mined around the world, there exists a wide variety of fancy colors.

They are also sіgnіfісаntlу аffоrdаblе thаn rare "соlorless" diamonds. J-L graded diamonds may also be a fantastic value for buyers on a budget because the yellow tint in these diamonds is only slightly noticeable and does not affect their overall appearance.
The planet's natural chemical interactions determine the color of diamonds because they are formed within the earth. Colorless diamonds are formed from carbon dioxide, but in rare instances, other minerals naturally meet the carbon during a stone's creation, creating various diamond colors. Different minerals that impact the carbon during its transformation into a diamond will produce unique colors. For example, rare blue diamonds, such as the famous Hope Diamond, result from the added mineral boron through the formation process.
While selling your diamond to a purchaser, color is always considered when determining its quality and value. The rarer and brightly colored stones are worth a premium because they are colorless. White diamonds are assessed using colorless diamonds as an industry standard and categorized on the GIA diamond grading system. An entirely separate evaluation takes place for fancy colored diamonds.

How to Select a Diamond Color before Buying
When buying a fancy-colored diamond, there are a few tips to bear in mind:
- Have a price range in mind because doing so will point you to the gem color and variety.
- Read a little on fancy colored stones to know how to select.
- Keep your options open when it comes to fancy colors since you may be unable to get a specific type of stone. However, there are many others up for sale that might be acceptable, if not better than the initial choice.
When looking fоr thе реrfесt dіаmоnd, it is important to find the elements that heavily influence the diamond's beauty and color. When you have selected the shape and cut, aspects like color can be brought into consideration. Moreover, as mentioned in this article, ensure that color does not require a front seat to your diamond.
