Lab-created diamonds are graded on their color using the same scale as mined diamonds, which ranges from D (colorless) to Z (light yellow). The color of a lab-grown diamond is determined by the impurities present in the diamond’s carbon lattice.
The most common impurities in lab-grown diamonds are nitrogen and boron. Nitrogen impurities cause the diamond to appear yellow, while boron impurities cause the diamond to appear blue. The amount of nitrogen and boron impurities present in a diamond determines its color grade.
Lab-grown diamonds with very few impurities will be graded as D, colorless. Diamonds with more impurities will be graded as lower color grades, such as E, F, or G. Diamonds with a lot of impurities will be graded as yellow or brown.
The color grade of a lab-grown diamond is determined by a gemologist using a grading microscope. The gemologist will look for the presence of any impurities and assess their color and concentration. The gemologist will then assign the diamond a color grade based on the GIA color grading scale.
It is important to note that the color grade of a lab-grown diamond can vary slightly depending on the grading laboratory. However, the GIA color grading scale is the most widely used standard, so it is a good benchmark to use when comparing the color grades of different lab-grown diamonds.
How to Choose the Right Color Grade for You
The color grade of a lab created diamonds is a personal preference. Some people prefer colorless diamonds, while others are ok with a slight tint. Ultimately, the best way to choose the right color grade for you is to see different diamonds in person and decide what you like best.
If you are on a budget, you may want to consider a lower color grade. However, it is important to remember that the color grade can affect the appearance of the diamond. A diamond with a lower color grade may appear slightly yellow or brown, especially when viewed under bright light.
If you are looking for a diamond with the highest possible color grade, you will need to pay more. However, a diamond with a D color grade will be colorless and will sparkle beautifully.
The color grade of a lab-grown diamond is an important factor to consider when choosing a diamond. The color grade determines how colorless the diamond will appear. If you are on a budget, you may want to consider a lower color grade. However, if you are looking for a diamond with the highest possible color grade, you will need to pay more.
