Everything You Need to Know About G Colored Diamonds

G colored diamondThe Gemological Institute of America (GIA) grades diamonds and one aspect they grade on is color. The GIA uses various letters to indicate the color grade. Starting with D, the highest grade indicating “Colorless,” the color grades go all the way to Z, which is the lowest. They then group these grades together in various color ranges. A diamond with a color grade of G is at the top of the “Nearly Colorless” range. Therefore, a D colored diamonds is also sometimes referred to as white diamond and doesn’t exhibit any body color.

Basic Facts About Diamond Color

  • A jeweler determines a diamond’s overall value in part on an absence of color (colorless).
  • A grading expert should always be the one who determines a diamond’s color grade.
  • Generally speaking, colorless diamonds are more valuable than colored diamonds.
  • The ring setting plays a big role in how the color of the diamond is perceived.

It’s important to know how the color grade of a diamond affects its value and appearance when you’re shopping for diamonds. Understanding this will help you distinguish the variations in the quality of the stones. You need to know which qualities determine the value and price of a diamond so you can get the most for your money.

GIA Color Scale Chart for Grading Diamonds

Diamond Color vs. ClarityThe Gemological Institute of America (GIA) is the most prestigious diamond grading organization issuing reports on diamonds.

When you’re buying a diamond, I highly recommend that you request a GIA certificate for each diamond you’re considering due to the broad range of colors you’ll likely see.

The GIA grading scale for Diamond Color is below:

Diamond Color Scale


A color grade of D is the highest, so these diamonds have almost no color. The look colorless when seen by the naked eye and under magnification. E and F color grades look nearly identical when seen by the naked eye. It takes an expert gemologist to distinguish between D, E, and F color grades.

D-F diamonds are typically set in white gold or platinum, as yellow gold or other metal settings would detract from the colorless quality of the diamond.

Nearly Colorless

Color grades G-J exhibit almost no color and to the naked eye look basically colorless. Although there may be a hint of color, these diamonds look best set in white gold or platinum due to the possible reflection of yellow gold on the diamond.

G-J diamonds are not as rare as D-F diamonds, so they cost less. In this range of nearly colorless diamonds, prices go down by about 10%-15% per grade but they may not look any different when seen by the naked eye.

Faint Tint

K-M color graded diamonds show a tiny hint of yellow when you look at it with the naked eye. People sometimes prefer the warmer tone in a magnificent yellow gold setting.

Due to their perceivable hint of color, diamonds falling in this color range often cost 50% less than G-I graded diamonds.

Very Light Tint

N-R color graded diamonds have a yellow to brown tone that you can see with the naked eye and therefore many vendors offer them at much lower prices.

I recommend that you avoid N-R color graded diamonds.

Light Tint

S-Z color diamonds have an obvious yellow or brown tone. This is why I do not recommend that you buy S-Z colored diamonds.


Engagement ring diamonds are typically in the nearly colorless range and may exhibit a slight yellow tint or brownish in tone. The diamond’s setting can change how the diamond’s color is perceived as does the lighting where the stone is being shown. It’s important that you keep these factors in mind when evaluating the color of any diamonds.

Does a G Colored Diamond Look Good?

G colored diamonds are nearly colorless, which means that you can detect only a tiny hint of yellow (if at all). This is not easy to see unless you do a side-by-side comparison with diamonds of a higher color grade. G color diamonds provide great value and look stunning in white gold or platinum settings. In general, it is absolutely ok to pair a g colored diamond with white metal. Even if you buy a diamond with high carat weight, such as 3 carat, you’ll still be happy with a g colored diamond. The same applies to emerald-cut diamonds.

Benefits of Choosing G Colored Diamonds

I can say with confidence that G colored diamonds appear colorless to the vast majority. So, is there some factor that sets these diamonds apart so that smart shoppers choose them over diamonds with a higher color grade?

It all comes down to a price! A G colored diamond can be much less expensive than those classified as colorless. In comparing prices, the difference can be hundreds or even thousands of dollars. If your budget won’t allow for a colorless diamond, a G color diamond is just one grade below, and you can have it for a lot less money.

Would a G colored diamond with VS2 clarity look impressive?

G colored diamond vs2 clarityDiamonds with a clarity grade of VS2 are in high demand because of their quality without a huge price. They have some tiny inclusions that can hardly be seen by the naked eye. You can only see these inclusions under a 10-times magnification but are insignificant. Diamond cut is far more important.

There are many different choices when it comes to diamond settings, so here is what I recommend for the diamond color grade, based on diamond-cut:

Ring Setting & Color Grade Recommendations

Solitaire Diamond in White Gold or Platinum Ring Setting 

If you select a round diamond with a higher color grade than H, you will pay for a feature that you cannot see with the naked eye, so it makes no practical sense. 

  • Round Cut: H-J color grades.
  • Asscher, Emerald or Princess Cut: G-I color grades.
  • All Other Cuts: F-H color grades.

Yellow Gold Ring Setting

The yellow-gold color of the setting is reflected onto the diamond, so any color grade above K would still appear slightly yellow.

  • Round Cut: K-M color grades.
  • Princess, Emerald, Asscher: J-K Grades.
  • All other Diamond Shapes: I-J Grades.
  • Asscher, Emerald or Princess Cut: J-K color grades.
  • All Other Diamond Cuts: I-J color grades.
  • Pave Side Stone or Halo Settings
  • Asscher, Emerald, Princess or Round Cut: G-I color grades.
  • All Other Diamond Cuts: F-H color grades.
  • For Halo Settings – All Diamond Cuts: F-H color grades.
