Diamond Color Scale Chart GIA

Posted by Vivek Kathiriya on

Everyone has a different preference of color, but it applied specially when it comes to buying a Diamond. One must keep in mind that a Diamond lasts longer than any other stone, so you must take care of the color while buying a diamond.

Diamonds are generally colorless, then how it gets colored? When crystals form inside the Earth, they take on the color of diamonds. The crystals can be colored by minute amounts of various elements, such as nitrogen. Additionally, the pressure used to make diamonds break the crystal. It is also thought to play a factor in their hue.

To make it easier for consumers, retailers, and diamantaires to comprehend how the color appearances of diamonds change over time, GIA has created color reference charts. Hue, tone, and saturation are the three terms used to describe color. Hue is the appearance of red, blue, or green, or anything in between (the relative strength or weakness of a color). Combining these three characteristics yields the color look of a gem. A color’s appearance can be located in color space by uniformly organizing these three characteristics. The tone/saturation charts display color in accordance with GIA’s organizational system. The reader will be better able to understand how GIA’s color descriptors and grades relate if they are familiar with this organizational structure.

Diamond Color Scale Chart

Don’t believe the myth that all diamonds are transparent or white. In reality, varied degrees of yellowish tinge can be found in the majority of diamonds. A diamond can be classified as having a color between D through Z, with D to F being colorless and hence the rarest and most expensive. The diamonds’ colors gradually darken as you move from Z on the scale.

  • Here, diamonds of grade D are completely colorless.
  • E and F have almost no color. Only professionals can tell the difference between D, E, and F when they unmount the diamonds since it is so little.
  • Less tint is visible in K, L, and M. When mounted, these diamonds look colorless.
  • There is a slight shade that is noticeable in grades N through Z.

 

Two Types of Diamond Color Charts

The majority of people react intuitively to color. However, the GIA has developed a methodical approach to examine diamond color in greater detail. The GIA, the most reputable diamond grading lab trusted by the whole world’s diamond industry, created the diamond color chart. The diamond’s color is one of the 4Cs and is clearly referred to in the diamond color chart, which was also created by the GIA. But when it comes to diamonds, there are two distinct coloring varieties. One is the spectrum of diamonds that range from colorless to yellowish, while the other is the realm of colorful diamonds. For each of these categories, there is a different diamond color chart, including a blue, black, and yellow diamond chart. In the recent past, colored diamonds have caused quite a stir in the world of diamond auctions. They are incredibly rare. Let’s begin by taking a look at the diamond color chart for colorless diamonds, though.

  1. Diamond Color Chart: Colorless Diamonds

The GIA Color chart spans the values D (colorless) to Z. (light yellow or sometimes brown). Opposing to popular belief, diamonds of jewelry quality don’t just come in colorless varieties. Since truly colorless diamonds are actually quite rare, most diamonds used in jewelry are either virtually colorless or occasionally exhibit faint yellow or brown hints. Since diamonds with a very small yellow tint are more frequently found in mines than diamonds that are totally colorless, D, E, and F color diamonds frequently command significant premiums. Based on how diamond grading laboratories assign color grades to loose diamonds, the GIA diamond color chart was developed.

Master stones are used to determine the color for each diamond color grade on the chart. Professionally graded diamonds are then compared to these master stones and given a color grade that matches a letter on the diamond color scale. Each letter grade serves as a representation of a spectrum of colors and a gauge for how prominent they are. But keep in mind that the diamonds were graded in ideal lighting and situations that were color-neutral. It won’t appear completely colorless if you set a F color diamond on a bright yellow ring band.

The color factor dominates the other ‘Cs’ when deciding the price of fancy-colored diamonds by a significant margin. The relationship between the various color appearances and how they impact color descriptions and grades is therefore crucial for you to comprehend.

The three qualities listed below are used to characterize color:

  • Hue
  • Tone
  • Saturation

A colored diamond’s combination of these three characteristics determines how it is graded by the GIA’s diamond grading specialists. The organization and classification of colored diamonds in relation to other colored diamonds is standardized by the GIA diamond color chart. While colored diamonds are definitely something special and need the assistance of experts to find, some colors, such as pink and red, are far rarer than others, such as yellow. Looking back at previous auctions, there is no doubt that interest in high net worth investing circles has grown.
