A lot of people have heard of the famous ‘4C’s’ of diamond buying and understand that color is one of the quality characteristics of diamonds. But in order to truly make the best decisions for your engagement rings and diamond jewelry, it is worth delving a little deeper and exploring these factors on an individual basis. A firm understanding of diamond color will not only prevent over-spending, but allow you to find the diamond color that suits your needs.

Positioned at the top of the ‘near colorless’ category of diamonds, a G color diamond is a highly popular choice for engagement rings. Why? Let’s take a closer look.

What is a G Colored Diamond?

Any diamond specialist or jeweler worth their salt will recommend certified diamonds; specifically, GIA or AGS certified diamonds. Certified diamonds are analysed by a gem lab and issued a corresponding certificate outlining their quality characteristics and their grades. One such grade is for the color of the diamond.

For an overview of diamond color I recommend reading my full guide to diamond color.

The GIA grades diamonds from D (colorless) down to Z. Gemmologists analyse the presence of any yellow/brown tints in the diamond (cause by the presence of nitrogen) and grade the diamond accordingly.

A G color diamond is at the top of the ‘near colorless’ category which also includes H and I color diamonds. The very faint yellow in a G color diamond will only be picked up by skilled gemmologists working in optimum lighting conditions using specialist equipment.

Do G Color Diamonds Look Yellow?

No. In normal lighting environments, and particularly when worn in jewelry, a G color diamond is barely distinguishable from the higher grades. It is just one grade away from F color diamonds which sit in the ‘colorless’ category.

Whether you’re opting for a rich, yellow gold setting or a lustrous white gold setting, a G color diamond will present as a bright white. As you can see in the image above,

G Color Diamond Prices

The popularity of diamonds in the ‘near colourless’ category is based on their wonderful balance of beauty and budget. The top three grades (D-F) are rare and it is this rarity which drives up the price. A G color diamond gives all the bright, white beauty of a higher-grade diamond, but at a fraction of the price.

As diamond prices fluctuate and are influenced by a multitude of factors.  I recommend taking a look at Blue Nile’s huge inventory of diamonds and using their filter tools to make quick and accurate comparisons of diamond prices. Remember that the Blue Nile inventory is virtual; this means that not all diamonds are available quickly and they won’t have been viewed in house. Whiteflash hold a huge collection of in-stock diamonds, which have been approved by their onsite experts and are available immediately. If you have concerns about the presence of color in a diamond, the knowledge that any diamond can be pulled from the Whiteflash inventory and examined is sure to offer some peace of mind. Use these industry leaders to make general comparisons when it comes to price.

Selecting a G color over a D color diamond can save you as much as 25%. You may wonder why anyone would spend more on the highest color grades for something that cannot be appreciated by eye. Diamond buying is personal. For some, the idea of owning something incredibly rare like a D color diamond is worth the additional investment. For others, they just want the best-looking diamond within their budget. There are no right and wrong answers; the choice is entirely yours.

Should I Buy a G Color Diamond?

G color diamonds are a wonderful choice for engagement rings, but they might not be right for everyone. Here are my tips:

Decide what to prioritize – Cut is indisputably the most important factor when it comes to diamond quality and should be prioritized in order to achieve the most beautiful diamond. Beyond this, it’s a matter of deciding what matters most to you.

Decide what can be compromised – In a perfect world, there would be no compromises! But realistically, pulling back on some grades can work better for your budget without compromising the beauty of your diamond. If a G color diamond is stretching your budget, you can comfortably look for H and I color diamonds for negligible color difference but a significant price difference.

Check certification – If you stray from the light and find G color diamonds offered at ‘too good to be true’ prices, double check their certification. Lower tier labs are known for overstating the quality of diamonds meaning you can end up paying more for a lower quality diamond.

Where to Buy G Color Diamonds

Look for vendors who sell GIA or AGS certified diamonds and also provide high-res images of their diamonds. This is a minimum requirement and you can quickly sift out lesser companies using these two simple steps. Going beyond this, I recommend considering ideal and super-ideal cut diamonds; with the experts doing the work for you, an exquisitely cut diamond guarantees an incredible sparkle. Take a look at Whiteflash and their A CUT ABOVE® diamonds for round brilliant and princess cut diamonds. For fancy shapes, Blue Nile’s inventory is unrivalled.
