When it comes to buying a diamond, color plays a crucial role in determining its value. The Gemological Institute of America (GIA) has established a color grading scale that ranges from D to Z, with D being the most colorless and therefore most valuable. In this blog post, we will explore the world of G colored diamonds, which fall in the middle of the scale. We will cover what makes G colored diamonds unique, their value compared to other colors, where to buy them, and how to care for them.

The Color Grading Scale:

The GIA color grading scale is widely used by the diamond industry to determine the color of a diamond. G colored diamonds fall in the middle of the scale, ranging from nearly colorless to a hint of yellow or brown. While they are not as rare or valuable as D colored diamonds, they are still highly sought after and admired.

What Makes G Colored Diamonds Special:

G colored diamonds are unique in that they often have a hint of warmth, giving them a beautiful and natural appearance. The color is caused by the presence of nitrogen in the diamond's crystal structure. G colored diamonds are also considered a great value because they offer a beautiful diamond at a lower price point compared to more colorless diamonds.

The Value of G Colored Diamonds:

While G colored diamonds are not as valuable as D colored diamonds, they are still highly sought after and can command a high price. The value of a G colored diamond is determined by a variety of factors, including the diamond's cut, clarity, and carat weight. G colored diamonds are often more affordable than D colored diamonds, making them a great option for those looking for a beautiful diamond without breaking the bank.

Is it Possible to Enhance the Colour of G Coloured Diamonds?

Yes, it is possible to enhance the color of G colored diamonds through a process called irradiation. This process involves exposing the diamond to high-energy particles such as gamma rays or electrons to alter the crystal structure and change the color. After irradiation, the diamond may undergo a heat treatment to stabilize the new color.

It is important to note that the process of irradiation and heat treatment must be disclosed to potential buyers and is typically indicated on the diamond's certification report. Enhanced diamonds are generally less valuable than natural diamonds and may not be as highly regarded by some consumers.

It is also worth noting that not all G colored diamonds are suitable for irradiation. The process is typically used for diamonds with a lower color grade, such as K or L, to improve their color to a more desirable shade. G colored diamonds are already considered to be of high quality, so enhancing their color may not be necessary or desirable in some cases.

Ultimately, the decision to enhance the color of a diamond should be carefully considered and discussed with a reputable jeweler or diamond expert. It is important to weigh the potential benefits of improving the diamond's color against the potential impact on its value and desirability among consumers.

Recent Sales of G Colored Diamonds:

In recent years, G colored diamonds have gained popularity among collectors and investors. In 2018, a 15.38 carat G colored diamond known as "The Sakura" sold for $29 million at a Hong Kong auction. This was a record-breaking price for a G colored diamond, demonstrating their increasing value and appeal to collectors.

Where to Buy G Colored Diamonds:

When it comes to buying G colored diamonds, it's important to shop with a reputable dealer. Look for a jeweler who has experience with diamond grading and has a GIA certification. Many online retailers offer a wide variety of G colored diamonds at competitive prices, but it's important to do your research and read customer reviews before making a purchase.

Caring for G Colored Diamonds:

Proper care and maintenance are essential for preserving the beauty and value of your G colored diamond. Avoid exposing your diamond to harsh chemicals and extreme temperatures, and clean it regularly with a soft-bristled brush and mild soap and water. It's also important to have your diamond professionally cleaned and inspected at least once a year to ensure it remains in good condition.

Conclusion

G colored diamonds offer a beautiful and unique option for those in the market for a diamond. Their natural warmth and lower price point make them a great value for those looking for a stunning diamond without the high cost of a more colorless stone. With proper care and maintenance, a G colored diamond can be a timeless and treasured piece of jewelry for generations to come.
