Diamonds are the focal point of any jewelry piece they are used in. That’s why there’s so much emphasis on finding the best possible diamond for your needs – one with excellent brilliance, clear color, and impressive size. With color being one of the most important factors in diamond grading and the G color grade being one of the best diamond color grades, it’s no wonder why G color diamonds are so valuable.

Below, we’ll delve deeper into the characteristics, pros, and cons of G color diamonds and we’ll determine whether they are worthy of their hefty price tags.

The Color Grading System

Diamond color grading chart

Established by the G.I.A. (Gemological Institute of America), this is the standard diamond color grading system used worldwide. It contains 23 different color grades that refer specifically to colorless diamonds. The further down the color grades we go, the more noticeable the yellow or brownish color of the diamonds are going to be. And since colorless diamonds are most valuable when they are colorless, the lower the color grade is, the less expensive the stone is going to be.

These are the basic color grades for colorless diamonds:

  • D, E and F – These diamonds are colorless and show no tints. These are also among the most expensive diamonds, all else being equal.
  • G, H, I  and J – These grades are known as near colorless diamonds. Of these, G is noticeably less yellow than a J.
  • K to Z–  These grades are faint yellow diamonds, increasing in intensity with each subsequent grade. Most retailers don’t sell diamonds below the M grade.

As you can see, G color diamonds fall on the border between the two best color categories. Naturally, this means that G is a very high and sought-after color grade but it also means that these diamonds are both rare and more expensive.

What Does a G Color Diamond Look Like?

G color diamonds are referred to as Near Colorless but a simpler way to look at that grade is as Essentially Colorless to the Naked Eye. However, unlike D-F diamonds, a G diamond will have a touch of warmth within it. When viewed from its side, this warm tint will be more visible. However, as engagement rings are typically viewed face up and not so much from the profile, your G diamond will typically look colorless once mounted in the setting.

G Color Grade vs. Other Color Grades

As they rest on the border between the Colorless and Near Colorless grades, G color diamonds can easily be mistaken for D, E or F diamonds as well as for H and I diamonds. G color diamonds are virtually indistinguishable from colorless stones to the naked eye, especially if you look at them from the top and/or when they are mounted on a ring.

You can easily test this by comparing a G color diamond with several F color ones at your local diamond ring retailer shop. Alternatively, you can take a look at the G color diamond selection of James Allen and compare it with their F color and H color selections. As long as you compare diamonds that are nearly identical in other categories such as carat, cut, and clarity, you’ll see that the exact color grade between F, G, and H doesn’t really make much of a noticeable difference.

However, while the visible difference might be minimal, the price difference can be very big.  For example, compare this G color diamond to this similar F color diamond. While they look near-identical, the difference in price is significant! Why pay for features you can’t see?  

All that being said, diamond purists will probably murmur that the difference between F, G, and H color grades is indeed significant. And we can agree with that – Colorless diamonds are even rarer than Near Colorless diamonds and rarity is a big factor in diamond prices and value.

So, if you’re looking for a diamond that’s rare for its collector and prestigious value, then there is a clear distinction between F, G, and H grades, and even more so for D and E grades. However, if you’re simply looking for a colorless diamond for your engagement ring, we’d suggest that you don’t need to get hung up on the exact color grade of the stone – if it looks good, that’s good.

Best Ring Settings for G Color Diamonds

An excellent way to downplay or flaunt a diamond’s color is by choosing the right setting and metal color to complement it. For colorless diamonds, white metals are considered the best as they don’t provide any contrast, whereas for warm diamonds, rose or yellow golds are often chosen because they make the diamond appear colorless by contrast.

The diamond in the yellow gold setting appears less warm than the one in the white gold setting, although both rings look beautiful.

What are the Pros and Cons of G color diamonds?

Let’s recap the advantages and disadvantages of this category of diamonds.

Pros:

  • G color diamonds are at the top of the Near Colorless diamond color grade and that makes them one of the best choices for a colorless diamond.
  • These stones possess almost all the visual qualities of D, E, and F color diamonds, especially when mounted on a ring, but they are not as ridiculously expensive.
  • Simply put, G color diamonds are gorgeous and can work very well with any type of setting and any metal color.
  • G color diamonds may not have the prestige of the D, E or F color grades but they are still a highly valued grade that you can be happy you own.

Cons:

  • As a high and valuable color grade, G color diamonds are quite expensive. If the price doesn’t concern you, that’s great, but if you’re looking for a bargain, there are lower color grades that are more affordable and offer a better beauty-value tradeoff, like the H, I, and J color grades. Even the K and L grades can make for a gorgeous engagement ring even though their color is noticeable to the naked eye – they just require some color and setting management for the ring but make up for that with a much more manageable cost.

Should You Get a G Color Diamond for Your Engagement Ring?

G color is a grade that always looks stunning and will give you the freedom to pick any ring design you want, including open settings such as solitaire ones that allow you to view the diamond from the sides.

If you’re on a budget, however, we’d recommend going for a lower color grade. In other words, if you opt for a slightly lower color grade such as I, J or even K or L, you can open some room in your budget for a higher carat size or a better cut.
