EDUCATION

If you have been looking at diamonds, but you’re unsure about where to start in regards to color, the following article will help you understand the differences.

 

The color of a particular diamond is considered one of the four main factors, or the four ‘C’s’ which determine the value of the diamond. The less color or cloudiness that a diamond has, the more expensive it is. A perfect diamond, color-wise, would be considered to be transparent, like glass, without any slight tints or shades. A perfectly clear diamond is one of the rarest to found, hence the extra value attached to them.

 

A perfect diamond is formed in nature; therefore, it isn’t an aesthetic consideration which determines how perfect it is. Diamonds are formed in nature following a specific process; often this process is interrupted which affects the color and formation of the diamond. This is what makes a perfect so hard to find. 

Information
  • Diamond color scale marked in letters English D-Z .
  • The more colorless the diamond or more "white" than it is more expensive.
  • Small diamonds and gem jewel and the uneducated eye, it is very difficult to distinguish the color of diamonds of the same category and adjacent categories Diamond color.

 

What Causes Color in Diamonds?

There are two main factors which can impact how a diamond is formed, and which could interrupt the diamond being formed and affect the color.

 

  • Foreign elements which were present during the formation process of the diamond could cause the diamond to be a certain color. These color-causing elements are called "trace elements.

  • Or, imperfections in the crystal structure caused during the formation process could create a certain color in the diamond.

It is because of these interruptions that a diamond wouldn’t have a perfect color, and they are much more common than a perfect diamond being created. Also, it is interesting to note that having a color may not affect the price of a diamond at all, depending on what it is. When a diamond has strong red, yellow, blue, or brown colors, it is considered a ‘fancy color diamond’ these are extremely rare. It is as high as one in ten thousand diamonds that are considered fancy color diamonds. 98% of diamonds only have a slight color, and these diamonds are worth as much as fancy color diamonds or perfect diamonds.

 

The Color Scale for Diamonds

 

The color grade isn’t fixed; it varies from diamond to diamond. The more a color is present in a diamond, the less it is worth. If a diamond has a varying range of color, it’s not considered a fancy color diamond, just an imperfect stone. The color grading scale for diamonds ranges from the letter D to the letter Z – D being the diamonds which are absolutely colorless, while Z denotes diamonds of a pale yellow or brown color. Yellow or brown diamonds that are darker than Z are considered to be in the category of fancy colored diamonds and therefore are more expensive.

 

Ultimately it is up to experienced, and qualified, gemologists to determine what color diamond is graded at. They compare the specific diamond to a master set of diamonds. All gemological labs have their own set of master diamonds. The different stones in the master set show the minimal amount of color a diamond may be allowed for its category. If a diamond is between to scales of color, it is automatically delegated to the better category. A diamond with a color between an I and J would, therefore, be an I.  

 

When a gemologist examines a diamond, they use a very specific lighting setup, or light box, which filters out all UV rays. To get the most accurate reading of a diamond’s color grading, it would generally be removed from any jewelry.

The grading scale is divided into several categories:

 

  • D – F: Colorless
  • G – J: Near Colorless
  • K – M: Faint
  • N – R: Very Light
  • S – Z: Light 

It is important to remember that with small, commercial diamonds which are set in jewelry, it is going to be very difficult to determine what color they are. This is great if you are looking at diamonds, but don’t have a large budget. You can take advantage of a diamond with a slightly worse color rating because you will never be able to discern the difference.

How to fit in my budget?
  • D-HSuitable for very high budget
  • F-GThe most lucrative in terms of value and price
  • H-IThe biggest in terms of size and price ratio
