Lab-grown diamonds can come in a broad spectrum of colors, from white to yellow, or even blue. And each variation represents a different level of desirability among buyers. With that in mind, here is a breakdown of what exactly makes up their colors.
What is diamond color?
Diamond color refers to the amount of color a lab-grown diamond contains. The more colorless a lab-grown diamond is, the higher its quality is.
It is pretty tricky to determine color distinctions with human eyes. Light source and background can also affect its color appearance. In a gemological laboratory, a lab-grown diamond will be color-graded against a set of master stones under controlled lighting and precise viewing positions.
“ Clarity, cut, carat, and color are all important factors in determining the value of a lab-grown diamond. These factors are also known as the 4Cs.”
The diamond color scale uses letters to grade its color. The scale ranges from D to Z, with D being completely colorless and Z being completely yellow. The letters correspond to the amount of color present in it.
What Is D Color Grade?
A D color is a lab-grown diamond that is colorless and has no tint of color whatsoever. It is also the best color. You’ll find that the majority of lab-grown diamonds that are sold have a color grade of D, as it is the closest to the color of pure graphite.
What Is H Color Grade?
H-color lab-grown diamond has a very slight yellow tint. This is a color that many people pick for their engagement ring, as it is still a very clear lab-grown diamond and doesn't need to spend a ton of money on it.
What Is N-Z Color Grade?
N-Z color lab-grown diamonds have a yellow tint to them. These are not transparent, but they are not entirely opaque either. This is why these N-Z colors are less valuable than a D or H color lab-grown diamond.
